ichnological evidences indicates that the rocks of Bhuban Formation exposed in Zuangtui area, Aizawl district of Mizoram were deposited under near shore high energy conditions. Key words: Ichnofossils; depositional environment; Bhuban Formation; Surma Group; Aizawl.

2024年5月5日 · In Afghanistan, surma (kohl) has been used since ancient times by both men and women to enhance the eyes, for its healing properties and to protect the wearer against the evil eye. Traditionally made by grinding stibnite rock into a fine power, the use of the black concoction to line the eyes also has a religious aspect.

2023年12月23日 · The Surma Group of rocks is N–S trending hill ranges, which developed along the Indo-Burma Ranges (IBR) and Chittagong Tripura Fold Belt (CTFB) as a result of the collision between the Indian plate and Burmese plate.

2021年4月2日 · In Mizoram, both Paleogene and Neogene sedimentary rocks are well developed which constitute the Surma Basin. This basin formed in response to the collision between Indian and Burmese plates similar to the evolution of the Bengal Basin (Ganju, 1975; Nandy et al., 1983; Dasgupta, 1984).

Surma Basin contains the maximum number of exposed litho-formations from the Eocene to Recent. The Kopili Shale and Sylhet Limestone (Eocene), the Barail Group (Oligocene), the Surma and...

2012年2月2日 · This study examines the various diagenetic controls of the Miocene Surma Group sandstones encountered in petroleum exploration wells from the Surma Basin, which is situated in the northeastern part of the Bengal Basin, Bangladesh.

2021年12月1日 · Here we use the technique to gauge the thermal maturity and the hydrocarbon source rock production index (PI) of each rock sample from the Surma Group. It is used for terrestrial source/organic rich rocks too and is an ideal analytical technique for the classification of marine source rocks (Sykes and Snowdon, 2002). Here we use the technique ...

2019年3月2日 · The Miocene molassic Surma sandstones in parts of the Naga-Manipur hills, in and around Nungba, Northeast India have been studied for their tectonic provenance using petrography and heavy mineral contents.

2022年6月1日 · The Miocene Surma Group is the oldest and most extensive sedimentary rock sequence exposed along the core of the anticlines in the EFB. The sedimentation of this group is associated with the repetitive cycles of marine transgression and regression ( Gani and Alam, 2003 ) and characterized by dark grey shale, siltstone and mudstone alternated ...

Among the reminders of the ancient Sar- matian Sea are coquina rocks that were formed by mineral, organic and sand particles. Constantly changing in response to wind and waves, coquina sometimes has unusual and bizarre shapes.

2021年5月31日 · Grey- to pinkish-colored Barail sandstone in the Surma Basin of Bangladesh is a good-quality reservoir rocks based on its petrophysical and petrographical analyses. Petrographic analyses shows that the studied sandstone samples …

2024年5月5日 · In Afghanistan, surma (kohl) has been used since ancient times by both men and women to enhance the eyes, for its healing properties and to protect the wearer against the evil eye. Traditionally made by grinding stibnite rock into a fine power, the use of the black concoction to line the eyes also has a religious aspect.

2021年9月1日 · rocks carried by upstream peaks at 5–13 Ma in the stratigraphic record suggesting that the monsoon was strong during this period (Clift and Plumb, 2008).

Surma Group of rocks. These rocks comprise of alternate beds of sandstone, shale, siltstone and mudstone of various thicknesses. The rock beds strike N-S and dip towards east and west in the northern and southern parts of the city respec-tively. The study area in Durtlang road section specifically exposes the Middle Bhuban Forma-

The Surma group of rocks are well-exposed in the steeper and faulted western flank as well as gentle and wider eastern flank of the asymmetric doubly plunging Sitakund anticline under the Chittagong district from Bariyadhala in the north to Barabkund in the south, which trends regionally in the NNW-SSE directions.

The present study analyzes the geochemical composition of sandstone and shale of the Miocene Surma Group to decipher the provenance, tectonic settings and paleoweathering condition of source area in…

2012年2月2日 · This study examines the various diagenetic controls of the Miocene Surma Group sandstones encountered in petroleum exploration wells from the Surma Basin, which is situated in the northeastern part of the Bengal Basin, Bangladesh.

2021年5月31日 · Grey- to pinkish-colored Barail sandstone in the Surma Basin of Bangladesh is a good-quality reservoir rocks based on its petrophysical and petrographical analyses. Petrographic analyses shows that the studied sandstone samples …

2020年8月28日 · The Oligocene Barail Sandstones of Surma basin from parts of Champhai District of Mizoram, northeast India has been studied for their tectono-provenance setting using petrography and geochemistry.
