Geology and geomorphology of Turkmenistan: A review

This article provides a background for scientists interested in a general overview of the geology and geomorphology of Turkmenistan. The basement of Turkmenistan is a complex amalgamation of arc-related terranes developed in the Asiatic and northern Paleotethys oceanic domains during Late Paleozoic to Triassic times. A major part of the country coincides with the Turan Platform, where a thick s...

Groundwater Modelling: from Geology to Hydrogeology

Three-dimensional mapping has extensively developed in the last decade; geological mapping being the area where these developments are more striking. 3D geological mapping has a myriad of applications in the domains of basin analysis, geophysics, geostatistics, geothermal and energy resources, etc. A parallel domain of development has been three-dimensional groundwater modelling: regional groun...

Karst Geology, Radon Fluctuations. and Implications for Measurement and Mitigation

Starting in December, 1996 and continuing through April, 1998, the Tennessee Radon Program, USEPA Region 4 Office, the Southern Regional Radon Training Center, and USEPA Headquarters conducted an investigation of several houses in Livingston, TN in which homeowners had discovered indoor radon concentrations far in excess of their original postmitigation test levels. The investigation team condu...

The Malayer plutonic complex: field geology, petrography and geochemical interpretation

The geochemical signatures like discordant variation of major and trace elements among felsic-intermediate and basic rocks  and  mafic enclaves of Malayer region on binary variation plots, decreasing values of FeOt, TiO2, MgO, MnO and CaO accompanied with increasing of SiO2 content from basic to felsic rocks, and decreasing Ni, Cr and Co with increasing SiO2 are considered as indications of mag...
