the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

The Witwatersrand Basin formed over a period of 360 Ma between 3074 and 2714 Ma. Pulses of sedimentation within the sequence and its precursors were episodic, occurring between 3086-3074 Ma (Dominion Group), 2970-2914 Ma (West Rand Group) and 2894-2714 Ma (Central Rand Group). Detritus was derived from a mixed granite-greenstone source of two distinct ages; the first comprises Barberton-type gr...

Despite salt being regarded as an extremely efficient, low-permeability hydraulic seal, increasing number of cross-evaporite fluid escape features have been documented in salt-bearing sedimentary basins. Because this, it is clear that our understanding how thick deposits impact flow basins incomplete. We here examine the causes and evolution northern Levant Basin, Eastern Mediterranean. High-qu...

This study has shown that increasing levels of insecurity often arise from basin closure. This was subsequently shown to be the situation in the South African case study, particularly in the Incomati River basin and to a lesser extent the Limpopo River basin. This study has also shown that these increasing levels of insecurity could result in the securitization of water resource management, whi...

The proximity of several recent earthquakes to the Los Angeles sedimentary basin provides an opportunity to isolate the effects of the basin on wave propagation. The 4 October 1987 aftershock (ML = 5.3) of the Whittier Narrows sequence and the 28 June 1991 Sierra Madre mainshock (ML = 5.8) are on a similar azimuth to stations overlying the deepest part of the basin. A distinctive feature of rec...

Champeh salt dome is located 30 km northwest of Bandar Lengeh, east Hormozgan province, Iran. Iron ores and several alterations can be found in this dome, which consists evaporitic volcanic sequences the Hormoz series Pabdeh-Jahrom, Asmari, Gachsaran, Mishan formations. The existing geological maps do not provide comprehensive details mineralization, alteration, various lithologies dome. Theref...

A maximum in the strength of Agulhas leakage has been registered at the interface between the Indian and South Atlantic oceans during glacial Termination II (T-II). This presumably transported the salt and heat necessary for maintaining the Atlantic circulation at rates similar to the present day. However, it was never shown whether these waters were effectively incorporated into the South Atla...

A program, INV2P5DSB, has been developed to simultaneously estimate the depth of a 2.5-D sedimentary basin and regional background from observed gravity anomalies. The density contrast is assumed to be varying parabolically with depth above the basement interface. The main program is supported with two subroutines GRAV2P5D and SIMEQ and a function GPRM. The analysis of gravity anomalies due to ...
