Discoveries of many coal seams at depths by drilling carried by Geological Survey of Pakistan in Sor Range and Harnai Gochina, extended the coal seams at depth which is challenge for mine owners to exploit feasibly. Bed to bed gypsum samplings (and their chemical analyses) of huge gypsum deposits from Sulaiman foldbelt is a base for industrialist and also planers to develop cement and gypsum industries to increase export and foreign exchange for the development of area and Pakistan. Low and high grade sedimentary iron deposits, silica sand and uranium host rocks and their extensions in Sulaiman and Kirthar foldbelts are presented. Anomalies of a few base metals arise as a result of geochemical exploration carried at part of Loralai District of Balochistan. Theropod dinosaurs were frequent in India, while Poripuchian titanosaurs (Sauropoda, Dinosauria) were frequent in Pakistan. Besides some ichnotaxa, many bone taxa such as 1 titanosauriform, 14 titanosaurian sauropod (including one new titanosaur), and 3 theropod dinosaurs are established from Pakistan. Among these 12 titanosaur species and 3 theropod species are named in about 10 km2 area of Vitakri dome and 2 titanosaur species are named in about a few hundred square meter area of Mari Bohri (Kachi Bohri) which is about 10 km westward from Vitakri dome. Pakistan is a unique country which discoverd 14 diversified titanosaurs in a short area and also in a short period (67 - 66 million years ago/Ma). About 400 bones found from a few meter thick upper part of upper shale horizon of latest Maastrichtian Vitakri Formation which is base for titanosaur taxa. Cranial material is in low fraction (but include significant diverse snouts), caudal vertebrae are prominent, the cervicals, dorsals and sacrals have significant numbers, forelimb and hind limb bones have balanced fraction. Humeri, femora and tibiae are most common. To know the position of Pakistani titanosaurs among titanosaurs and sauropods, there is a need to extend list of characters for phylogeneti

Plates Boundary and Structural Geology of Balochistan and Indus Basins through Field Observations on Chaman Transform Fault and Western Indus Suture (Pakistan): Dinosaurs from Pakistan with Attributed Bones and Key Features: titanosaurs from India with Updated Assessment on Jainosaurus

The plate boundary between Balochistan and Indus basins is found on the position where Western Indus Suture and Chaman Transform fault converge in the south (Uthal-Bela-Ornach-Nal-Basima). From Basima to northward the both structures bifurcate and separate more than 50 km in the Zhob region, the Chaman Transform fault lies in the west as straight way in flysh and slates of Balochistan basin, and Western Indus suture lies in the east mostly straight and wide (more than 20 km wide) galaxy way like belt (gentle wavy in the central portion from Quetta to Zhob). Plate boundary between Balochistan basin and Indus basin lies in the Western Indus suture. The both structures are about 1000 - 1500 km trends northward. The northward bending of strikes in the southern Balochistan basin (from Arabian sea to Kharan) on the western flank of Chaman transform fault and dragging of Kharan limestones revealed left lateral strike slip fault. The structures of Balochistan basin are mostly imbricated while the structure of Indus basin is mostly folded. Different basins in Pakistan yielded dinosaurs and diverse Mesozoic vertebrates like poripuchian titanosaurian sauropods, vitakrisaurid abelisaurian theropods, induszalimids, sulaimanisuchid and mithsaraikistanid mesoeucrocodiles, saraikisaurid pterosaurs, wasaibpanchid bird, madtsoiid snake, zahrisaurid plesiosaur and some fishes. From Pakistan 10 titanosaurs were named while from India 5 titanosaurs were named and discussed here. The updated assessment for the attribution of bones to Jainosaurus septentrionalis resulted the braincase its type or in other case braincase and scapula referable to Isisaurus colberti matching its long articular surface for coracoid of distal scapula. Key bones which were previously referred to Jainosaurus septentrionalis belong to mostly Gspsaurus pakistani and Balochisaurus malkani (stocky titanosaurs) and a few bones to Isisaurus colberti and Pakisaurus balochistani (slender titanosaurs).

Geology and Mineral Deposits of Saraikistan (South Punjab, Koh Sulaiman Range) of Pakistan: A Tabular Review of Recently Discovered Biotas from Pakistan and Paleobiogeographic Link: Phylogeny and Hypodigm of Poripuchian titanosaurs from Indo-Pakistan

引用

Open Journal of Geology 2023年第8期13卷 900-958页

作者： Muhammad Sadiq Malkani Geological Survey of Pakistan Muzaffarabad Pakistan

Saraikistan (South Punjab and surrounding) area of Pakistan is located in the central Pakistan. This area represents Triassic-Jurassic to Recent sedimentary marine and terrestrial strata. Most of the Mesozoic and Early Cenozoic are represented by marine strata with rare terrestrial deposits, while the Late Cenozoic is represented by continental fluvial deposits. This area hosts significant mineral deposits and their development can play a significant role in the development of Saraikistan region and ultimately for Pakistan. The data of recently discovered biotas from Cambrian to Miocene age are tabulated for quick view. Mesozoic biotas show a prominent paleobiogeographic link with Gondwana and Cenozoic show Eurasian. Phylogeny and hypodigm of Poripuchian titanosaurs from India and Pakistan are hinted at here.
