TY - THES A1 - Carls, Hans-Georg T1 - Das hochmittelalterliche Seefernhandelszentrum von Hormoz T1 - The highmedieval longdistance Seatradecenter of Hormoz N2 - Das Hauptziel dieser Studie war, den Standort des 1 300 A.D. vom iranischen Festland auf die vorgelagerte Insel Jarun (später Hormoz) verlegten Seefernhandelszentrums von Alt-Hormoz zu belegen. Dieses Ziel sollte über einen interdisziplinären Ansatz mit Hilfe von kulturgeographischen, siedlungsarchäologischen, historischen und geowissenschaftlichen Methoden erreicht werden. Bisherige archäologische und geographische Studien kamen zu sehr unterschiedlichen Standortangaben. Aus diesen Gründen wurde das Untersuchungsgebiet an der hochariden Schlickwattküste der heutigen Straße von Hormoz auf eine ca. 10 Quadratkilometer große Fläche ausgedehnt. Der Name Seefernhandelszentrum von Alt-Hormoz steht für das 1300 AD verlassene, festländische Fernhandelszentrum. Der Name Neu-Hormoz steht für das ab 1300 AD auf der Insel Jarun gelegene Seefernhandelszentrum. Auf der Insel Jarun gibt es kaum Vegetation und so gut wie keine Trinkwasserquellen. Man kann hier von einer für Mensch und Tier äußerst lebensfeindlichen Umwelt sprechen. Die zeitliche und funktionale Zuordnung der im Rahmen der Feldarbeiten im Gebiet des ehemaligen Seefernhandelszentruns von Alt-Hormoz lokalisierten Fundorte basiert auf voneinander unabhängigen Auswertungen verschiedener Oberflächen- oder Kleinlesefund-gruppen (qualitativer Ansatz). Eine zentrale Stellung nahmen dabei fernöstliche Keramiktypen ein. Es wurde aber auch islamische Keramik mit in die Auswertung ein bezogen. Um die über die fernöstliche und die islamische Keramik gewonnenen Erkenntnisse abzusichern wurden auch chinesische Münzen datiert.. Da Alt-Hormoz im 13. Jahrhundert eine Münzstätte war ließen sich zahllose islamische Münzen nachweisen, wovon ein Teil datierbar war und in erster Linie der Münzstätte Alt-Hormoz zugeordnet werden konnte. Diese materiellen Überreste aus der 1300 AD verlassenen Hafenstadt Alt-Hormoz unterscheiden sich signifikant von denen, wie sie am Standort des Seefernhandelszentrums von Neu-Hormoz (Insel Jarun) aus dem 14. und 15. Jahrhundert bekannt sind. Die Qualität und die Quantität der am Fundort Kalatun (Alt-Hormoz) an der Oberfläche nachgewiesenen Baumaterialien lassen überhaupt keinen Zweifel daran, dass es sich hier um die architektonischen Überreste einer historischen Hafenstadt handelt, deren Bewohner am einträglichen, internationalen Seefernhandelsgeschäft partizipierten. N2 - The intention of this research has been to verify the displacement of the longdistance seatrade centre of Old-Hormoz from continental Iran to the island Jarun (later called Hormoz) in 1300 A.D. This intention should be reached with an interdisciplinary proceeding including geographical, archeological and geoscientifical methods. Hitherto existing archeological and geographical studies lead to very different results about the location of the centre. Because of this reason the area of interest at the arid coastal-zone near the present Strait of Hormoz has been enlarged to a territory of about 10 square kilometers. The expression longdistance Seatradecenter of Old-Hormoz relates to the continental Long-distance Tradecenter which was left in 1300 A.D. The expression New-Hormoz is related to the longdistance seatradecentre which was new established in 1300 A.D. on the island of Jarun. On this island there is no vegetation and there are nearly no sources of drinking-water. One could talk about an environment with an extreme hostility against lives of human beings and animals. The temporal and functional attachment of the archiological sites located during the field study is based on independent analysis of different surface finding-groups (qualitative proceeding). Far Eastern Ceramic-Types have been positioned in centre. But the interpretation also includes Islamic Ceramic. To be on the safe side the investigated determinations from the Far Eastern and the Islamic Ceramic also Chinese coins have been dated. Because Old-Hormoz was a mint, countless Islamic coins have been proofed. Some of them have been datable. Most of them have been attached to the mint of Old-Hormoz. These archaeological remains from the site of the harbour city of Old-Hormoz, which has been abandoned in 1300 AD, do distinguish significant from those, which are well known from the site of New-Hormoz (Island of Jarun). There is no doubt, that the quality and quantity of the archiological surface findings of building material from the site of Kalatun (Old-Hormoz) are the remains of a large mediaeval seatrade centre of the thirteenth century A.D.. The inhabitants of these type of towns did participate a lot of the profitable international longdistance seatrade.

The composition of sandstones, and heavy mineral analysis point to pre-existing sedimentary, low, middle to upper rank metamorphic, and plutonic rocks of the Kalmard, Posht-e-Badam, Bayazeh, and Zarand-Kerman areas as the source rocks. According to the diagram of WELTJE et al. (1998), most samples from the Middle-Upper Jurassic rocks suggest a moderate to high elevation of the source area, and indicate a semi-arid and mediterranean to sub-humid climate. In the Qt-F-L ternary diagrams of DICKINSON et al. (1983), most point counting data from the Lower Siliciclastic Member and the top of the Hojedk Formation plot in the recycled orogen (Quartzose recycled) area of the diagram. The sandstones in this area can be interpreted as being derived from the Mid-Cimmerian Movements. Sixteen different types of siliciclastic-carbonate, and evaporatic sedimentary environments have been recognized. Thirty-nine macroinvertebrate taxa have been identified. Ten ichnotaxa have been taxonomically described from the Middle to Upper Jurassic rocks. Quite likely, before rotation of CEIM which were associated with counterclockwise block-rotation, equivalent rocks of the Bidou Formation occurred along the tectonic zone between the Yazd and the Tabas blocks (probably during the Middle Jurassic to Lower Cretaceous). However, from the Cretaceous onwards, most of the Bidou Formation has been removed by a combination of strike-slip and reverse movements of the Kashmar-Kerman tectonic zone. Roughly, these block-rotation movements occurred after the Cretaceous. During the Middle to Upper Jurassic, the tectonic activities were vertical movements producing the sedimentary pattern in the CEIM.

The thickness ranges from less than 300 m in a deltaic succession (Kuh-e-Radar) to more than 2500 m in the Maiamay area, but the normal thickness in Ghal-e-Sangi, Kol-e-Malekabad, and Fraizi areas is about 1200-1300 m. It is the fill of an elongated basin, which extended for more than 200 km in NW-SE direction and a width of at least 50 km along the southern margin of the Koppeh Dagh. Prior to this study, little information existed about the sedimentary environments and other characters, especially the geometry of the basin. Exact biostratigraphic data from the top of the Kashafrud Formation were rare. Based on the macrofauna from the lower part of the overlying Chamanbid Formation the upper boundary of the Kashafrud Formation had been attributed to the Late Bathonian and/or Early Callovian, but now the upper limit of the Kashafrud Formation is defined as Late Bathonian in age, based on ammonite biostratigraphy. Except for chapter one, which deals with the introduction and related sub-titles, in the following chapters, step by step, field observations and data were surveyed according to the questions to solve. In order to reconstruct the facies architecture and the geometry of the basin, a number of sections have been logged in detail (see chapter 3, “The sections”). The exact biostratigraphic setting is discussed in chapter 4 (“Biostratigraphy”). Sedimentary environments range from non-marine alluvial fans and braided rivers in the basal part of the succession to deltas, storm-dominated shelf, slope and deep-marine basin. The latter comprises the largest part of the basin fill, consisting of monotonous mudstones, siltstones and proximal to distal turbidities. The only continuous carbonate unit (~30 m) locally formed at Tappenader. Other localities in which thin fossil-bearing carbonate strata occur are Torbat-e-Jam (benthic fauna) and, to a lesser extent, Ghal-e-Sangi. These rare shallow-water carbonates, which also contain corals, represent only short intervals (see chapter 5,” Facies association and sedimentary environments”). Relative changes in sea level were reconstructed on the basis of deepening- and shallowing-upward trends. Sequence boundaries and parasequences have been distinguished and analyzed in chapter 6 (“Sequence stratigraphy”). In most areas, the basin rapidly evolved from a shallow marine, transgressive succession to a deep-marine, basinal succession. The only area where shallow conditions persisted from the Late Bajocian to the Late Bathonian, and even into the Early Callovian is the Kuh-e-Radar area which corresponds to a fan-delta setting. A trace fossil analysis has been carried out to obtain additional evidence on the bathymetry of the basin (see chapter 7, “Ichnology”). Altogether 29 ichnospecies belonging to 15 ichnogenera have been identified, as well as 10 ichnogenera, which were determined only at genus level. They can be grouped in the well-known “Seilacherian ichnofacies”. Very high subsidence rates and strong lateral thickness variations suggest that the Kashafrud Formation is a rift related basin that formed as the eastern extension of the South Caspian Basin. The basin evolution is reviewed, the eastern and western continuations of the basin were checked in the field and also in the literature (see chapter 8, “Basin evolution”). In all, the present study provided new insights into the development of the Kashafrud Formation, e.g. more biostratigraphic data from the base and the top of the succession, a relatively complete picture of the trace fossil associations, a better recognition and reconstruction of the sedimentary environments in different parts of the basin. Finally this research project will be a good basis for further investigations, especially towards the west, as parts of the Kashafrud Formation are source rocks of a hydrocarbon reservoir in NE Iran.
