“…Based on the detailed investigation, it is possible to conclude that the Kuldana Formation originated in a neriticdeltaic environment with a northern source (Figures 2 and 15). Previous researchers observed the presence of gastropods (pyramidellidae), miliolids, Nummulites, Lockhartia, ostracods, bivalves, brachiopods, Lockharia pustulosa, and Neorotalia viennoti [31,32]. They assigned the Middle Eocene age to the Kuldana Formation.…”

“…They further proposed that the detritus of these sediments was derived from the Kohistan-Ladakh arc (KLA), the Lhasa Block (LB), and the Karakoram Block (KB) of the Asian terrane. Previous researchers also recovered the fossils of vertebrates, foraminifers, bivalves, and gastropods from various sections of the Kuldana Formation [31][32][33]. The petrography of detrital sandstone rocks is an important method for determining siliciclastic rock provenance and pinpointing mineralogical composition.…”

Petrography and Provenance of the Sub-Himalayan Kuldana Formation: Implications for Tectonic Setting and Palaeoclimatic Conditions

In this paper, the depositional environment, age, and tectonic context of the Sub-Himalayan Kuldana Formation are discussed in detail. To determine the Kuldana Formation’s depositional environment, age, and tectonic setting, sedimentological, palaeontological, and petrographic investigations have been conducted accordingly. The Kuldana Formation lithologically consists of both siliciclastic and carbonate rocks. Petrographically, the Kuldana Formation’s sandstone is divided into litharenite and feldspathic litharenite petrofacies. The sandstone plots on the QtFL and QmFLt suggest that the sandstone of the Kuldana Formation derived from a recycled orogen provenance field that developed during the collision of the Indian and Eurasian plates in the Lesser and Higher Himalayas. The plots in the diamond diagram further demonstrate that the detritus of the Kuldana Formation was derived from low and middle-to-upper rank metamorphic rocks of the Himalayas. Throughout the deposition of sandstone, paleo-climate conditions were semi-humid to semiarid. Dolostone and limestone are the two main types of carbonate rocks found in the Kuldana Formation. According to Dunham’s Classification, the Kuldana Formation limestone is classified as mudstone, wackstone, and packstone. These petrofacies suggest that the limestone was deposited in an inner-outer ramp setting. The bioclasts include bivalves, brachiopods, crinoid, gastropods, Globigerinoides spp, Lockhartia pustulosa, miliolids, Nummulites atacicus, Nummulites discorbina, Nummulites mamillatus, Nummulites djodjokartae, Nummulites vascus, and ostracods suggesting that the age of Kuldana Formation is Middle Eocene- early Oligocene. The Kuldana Formation was deposited during the initial stages of the Himalayan Orogeny as a result of the Ceno-Tethys Ocean’s regression and transgression, as revealed by a succession of siliciclastic and non-clastic rocks.

A feasibility study by the Tennessee Valley Authority indicated that near surface material from the lower bed could be beneficiated; material in the subsurface zone contains a good deal of clay which interferes with the beneficiation process, and the feasibility of use of the material has not been proved (Meissner and Ankary, 1972).…”

The Arabian Shield is underlain by rocks that range from Precambrian through Phanerozoic (Brown and Jackson, 1960; Schmidt and others, 1973; Greenwood and others, 1973; Greenwood, Roberts, and Bagdady, 1974 ). The geology discussed herein is based on a report by Greenwood and others (unpub data) with several significant differences in interpretation favored by Roberts. The lithologic units, tectonism, plutonism, and metallogenic epochs are summarized in table 1.
