The Kırka borate deposit (Miocene), in western Turkey, the most important B2O3 producer at present in the world, exhibits a symmetrical zonation in a lateral sense; it is comprised of: a central body of Na borate (borax), an intermediate zone of Na–Ca borate (ulexite), and a marginal zone of Ca borate (colemanite). This mineral zonation is also developed in a vertical sense, although it is some...

conclusions tuberculosis was an important cause of cap in our region. hence, it should be considered in all patients admitted with a cap diagnosis. results among 120 patients with cap, the most common etiology was s. pneumoniae (24.4%), followed by mycobacterium tuberculosis (17.5%), s. aureus (6.7%), polymicrobial agents including anaerobes (4.2%), complicated hydatid cyst (2.5%), influenza a ...

This study aimed to find the depositional environment and formation conditions of gypsum-dominated Miocene succession alternated intercalated with clastics carbonates in southwestern part Erzincan Basin. As a result sedimentological, mineralogical-petrographic investigations, it was determined that gypsum this sequence formed as primary secondary. Primary lithofacies; nodular anhydrite, selenit...

Episodic venting from deep overpressured layers has rarely been documented in sedimentary basins, so the pressure evolution leading to these cyclical phenomena is poorly understood at present. Using three-dimensional (3D) seismic data West Nile Deep Sea Fan, we interpret >480 fluid escape pipes within a region of prolific leakage across > 2 km thick sealing sequence salt and claystones. Within ...

To promote oil and gas exploration of the Carboniferous formation in Shibei sag, northeastern margin Junggar Basin, recently drilled rocks from Well ZB6 with typical seismics were characterized. Through systematic core observation, identification marks seismites described, a vertical sequence was established, its geological significance analyzed. The results show that have marks, such as soft-s...
