Phân tích kiểu hình, môi trường lắng đọng và địa tầng chuỗi tương quan của tầng Gachsaran tại Tây Nam Iran Dịch bởi AI Springer Science and Business Media LLC - Tập 35 - Trang 1-28 - 2020
Reza Mirzaee Mahmoodabadi
Thế Miocene dưới tại Tây Nam Iran bao gồm tầng Gachsaran. Tầng này cấu thành một trong những lớp vỏ chính của các hồ chứa dầu tại Tây Nam Iran, bao gồm một chuỗi dày đặc các đá bốc hơi trong bể Zagros. Nghiên cứu này trình bày phân tích kiểu hình, môi trường lắng đọng và địa tầng chuỗi tương quan tại Tây Nam Iran. Để nghiên cứu về kiến trúc đá học, kiểu hình, môi trường lắng đọng và địa tầng chuỗi...... hiện toàn bộ
Investigation into rock moisture and salinity regimes: implications of sandstone weathering in Yungang Grottoes, ChinaSpringer Science and Business Media LLC - Tập 30 - Trang 1-11 - 2014
Fang Guo, Guanghui Jiang
Yungang Grottoes in north of China are the classical masterpieces of Chinese Buddhists, dating from the Northern Wei Dynasty 1,500 years ago. This rock art is threatened by weathering processes that has been accelerated due to coal mining. The dominant weathering processes occurring on the rock surface are collapse, flaking, and efflorescence. Salt crystal growth plays a major cause of these deter...... hiện toàn bộ
Genesis of tepees in the quaternary hardpan calcretes, Mersin, S TurkeySpringer Science and Business Media LLC - Tập 22 - Trang 123-134 - 2007
Muhsin Eren
In the Mersin area, the calcretes are widespread and occur in a variety of forms. The upper surface of the hard laminated crust (hardpan calcrete) represents a distinctive surface morphology of dome-like or slightly elongated dome-like and rarely ridge-like morphologies. These antiformal surface morphologies are interpreted as calcrete-tepee structures. Their cross-sections appear as an upward buc...... hiện toàn bộ
Description of the reservoir along strike-slip fault zones in China T-Sh oilfield, Tarim BasinSpringer Science and Business Media LLC - Tập 36 - Trang 1-12 - 2020
Rui Zhao, Shang Deng, Lu Yun, Huixi Lin, Teng Zhao, Chen Yu, Qiangfu Kong, Qiang Wang, Huili Li
The reservoir depth of T-Sh oilfield in Tarim Basin is more than 7500 m, which is a typical deep carbonate fault-controlled reservoir. The S-1 and S-5 fault zones experienced multi-stage tectonic movements and developed complex fault-fracture systems. Based on geometry and dynamics, the evolution characteristics of faults are analyzed; the permeability of strike-slip faults in the middle and lower...... hiện toàn bộ
Ventilation effects in a karstic show cave and in its vadose environment, Nerja, Southern SpainSpringer Science and Business Media LLC - Tập 26 - Trang 11-17 - 2011
José Benavente, Iñaki Vadillo, Cristina Liñan, Francisco Carrasco, Albert Soler
This study deals with the process of CO2 exchange between karst systems and the atmosphere, which is an important issue in the global carbon cycle and in climate change estimations. The study is focused on CO2 measurements in the Nerja Cave (south Spain) and in a number of research boreholes located nearby during the 2006–2008 period. Nerja is an important show cave, with some 500,000 visitors per...... hiện toàn bộ
Deep karst system research, Michigan, USASpringer Science and Business Media LLC - Tập 27 - Trang 119-122 - 2012
Tyrone J. Black
At least three major evaporite dissolution events have developed deep karst in two zones of the northern Michigan basin. Dissolution of outer margin Silurian evaporites resulted in the Mackinac Breccia during the early Devonian. This rebound and exposure or a later, brief basin rebound also caused the development of surficial evaporate epikarst in the middle Detroit River Group before the next sub...... hiện toàn bộ
Karstic gypsum problems at wastewater stabilization sites in the Black Hills of South DakotaSpringer Science and Business Media LLC - Tập 12 - Trang 73-80 - 1997
Arden D. Davis, Perry H. Rahn
The Triassic Spearfish Formation contains numerous gypsum beds in which karstic conditions have developed in the Black Hills of South Dakota. The evaporite karst has caused severe engineering problems for foundations and water retention facilities, including wastewater stabilization sites. Two dramatic examples include the former sewage lagoons for the City of Spearfish and a proposed lagoon/wetla...... hiện toàn bộ
Environmental characteristics of karst in China and their effect on engineeringSpringer Science and Business Media LLC - Tập 28 - Trang 251-258 - 2013
Yaoru Lu, Qi Liu, Feng’e Zhang
Due to the diverse geology and environmental conditions in China, karst development is characterized by great variety and regional regularities. At the same time, the engineering effect involved in the construction and development work undertaken in karst regions varies considerably. This article describes the regional characteristics of karst development in China, analysis of its karst hydrogeolo...... hiện toàn bộ
Carbonate geochemistry and mineralogy of short cores, Gulf of Suez, EgyptSpringer Science and Business Media LLC - Tập 11 - Trang 155-161 - 1996
Amr A. El-Sammak, Mohammed N. Shaaban
The present paper deals primarily with the mineralogical, geochemical and isotopic characteristics of some modern carbonate sediments recovered from four short cores from the Gulf of Suez off Sukhna. These cores lie between 32° 44′ and 32° 48′ E and 28° 58′ and 29° 16′ N. The paper aims to figure out the various controls on the minerals accumulation in the Gulf of Suez and to evaluate the chemical...... hiện toàn bộ
