The most enigmatic problems with the nearly 200 salt domes pierced in the Persian Gulf and in the Zagros Mountain Ranges (ZMR) in southern Iran, a unique morphology in the world, have been the matter of this study, which is based on a combination of field work, enhancement of satellite and aerial photographs etc. In the ZMR, structural anomalies are frequently associated with similar facies distribution patterns. In the eastern portion of the region, emergent salt plugs of Infra-Cambrian age exhibit the same alignment patterns. Such trends bear no apparent genetic relationship to the Tertiary folding responsible for the present Zagros fold belt, but rather indicate their affinity with linear basement features which are readily observable on Land sat imagery and aerial photographs. Bending of anticlines in the competent cover rock, combined with minor strike-slip faults and horizontal displacements of parts of folded structures, strongly point to the presence of these basement faults. The salt plugs, which have pierced cover rocks of up to 10000 m thick, are distributed on the Arabian Platform along regional basement faults. The area of diapir outcrops is bounded by the Oman Line to the east and by the Kazerun fault to the west. Pieces of the basement have been brought up to the surface on some of the salt domes. The fragments were transported by rotational ascent of the Hormuz Salt Formation to the present and former land surfaces. The recognition of features related to basement tectonics and realization of their implication in the control and modification of geological processes are important adjuncts to the search for hydrocarbon accumulations in this region. To our best knowledge, data of basement faults in the study area are scarce. Therefore, this study was carried out to determine basement faults and their relation to salt dome distribution. Considering the fold axes bending, the trend of the salt plugs and also the distribution of epicenters of the last century, n umerous new basement faults are introduced in this paper.

In a survey on the edaphic mesostigmatic mites in mangrove forests of Qeshm Island, eastern of the Persian Gulf, two species of the family Ascidae were collected in broken cockleshells and sand in littoral zone: Leioseius sepidehae sp. nov. and Protogamasellus mica (Athias-Henriot, 1961). This is the first record of the genus Leioseius from Iran. Leioseius sepidehae sp. nov. is described from adult females. Intraspecific variations of some characters of P. mica are discussed, and based on those, P. primitivus machadoi Genis, Loots & Ryke, 1967 and P. primitivus similis Genis, Loots & Ryke, 1967 are herein synonymized under P. mica. Finally, the occasional presence of the gland pores gv1 in Ascidae is reviewed, and a key to the Iranian genera and species of Ascidae is presented.

Geographically, Iran is for the most part a plateau at an average altitude of about a thousand metres; the terrain—the near-jungle conditions of the Caspian littoral excepted—is arid semi-desert and the typical landscape one of limestone mountain ranges between which lie flat plains. It is bordered by Iraq, Turkey, the U.S.S.R., the Caspian Sea, Afghanistan, Pakistan and the Persian Gulf. Except during spring the vegetation in most areas is sun-shrivelled on the bare treeless earth; after five months of burning heat the winter rainfall washes off the topsoil, and river-beds, dry throughout the summer, overflow with muddy torrents. Although the soil is dry and powdery there are abundant watercourses below the surface and with irrigation the land is very productive. The country has great mineral resources; apart from the oil-fields they are un-exploited due to lack of coal and road and rail communications. The people are mainly feudal villagers or nomadic tribesfolk but Tehran is a modern city of a million population and the provincial capitals are also semi-Westernized.

Aphanius pluristriatus (Jenkins, 1910) (Cyprinodontidae) is a poorly known species from Fasa, located in the Mond Riverdrainage system, east of Shiraz, southern Iran. It has not been investigated since its first description, its validity has beenquestioned and a synonymy with A. sophiae (Heckel, 1849) has been suggested. In this study, we describe a new collectionof Aphanius specimens from the Zarjan spring system, which is probably the same spring system from where Jenkins(1910) collected the type specimens of A. pluristriatus. The morphological characters of our new series of specimens areconsistent with those of A. pluristriatus as originally described by Jenkins (1910). We emend the original description ofA. pluristriatus and add morphometric and meristic data. A comparison with the related taxa A. sophiae, A. farsicus (for-mer A. persicus) and A. isfahanensis reveals that A. pluristriatus can be separated from them by a smaller caudal peduncleindex, higher number of flank bars, lower number of gill rakers, and higher J scale index. Therefore A. pluristriatus rep-resents a valid species, which is at present restricted to the drainage system of the Mond River. We suggest that A. pluris-triatus originated from an ancient A. sophiae population in the Kor River Basin during the Quaternary. At that time, theKor River was draining to the Persian Gulf by the “Paleo-Kor River” and the Mond River. During the Late Quaternary orHolocene, the connection between the Kor River and the Persian Gulf has been blocked as a result of tectonic uplift (theKor River Basin is endorheic today). Thus, A. pluristriatus most likely is the relict of an ancient Aphanius population from the Quaternary “Paleo-Kor River” drainage system.

This chapter considers issues of race and ethnicity in Iran, as well as in its borderlands with Iraq and the Persian Gulf. It interrogates the concepts of "Arabness" and "Persianness" as espoused by both indigenous and Western writers, especially in the nineteenth century when the academic interest in race and language gained popularity. The chapter parses anthropological assumptions about the differences in the racial and ethnic communities of southern Iran, Iraq, and the Persian Gulf and traces the ways in which these ideas gained fluency in political tracts and state-building efforts. Finally, the chapter argues that racism remained problematic in Iranian popular culture despite the country's solidarity with many Afro-Asian liberation movements in the second half of the twentieth century.
