The paper presents the latest state of knowledge on clastic sedimentary rocks from Carboniferous complex in SW part Polish Lowlands, studied to help determine their potential prospectivity for occurrence oil and/or gas deposits. Rocks were analyzed with respect petrographic-mineralogical characteristics deposits, diagenesis, determinations pressure-temperature conditions mineral formation and h...
The Oligocene–Miocene deposits of the Asmari Formation are located in SW of the Zagros Mountains of Iran. The lower part of the Asmari Formation consists of an evaporite bed that is termed Basal Anhydrite. Seven sections from four different anticlines were selected and sampled for petrographic and mineralogical analyses .The petrographical examinations were carried out using an optical polarize...
The Sibzar Formation (Middle Devonian) is located about 30 km east of Neyshabur and is composed of lower dolostone with intercalations of sandstone, middle basaltic sill and upper dolostone to limy dolostone, with a thickness of 334 m. Based on the crystal size in this formation, three different types of dolomite (D1, D2, Vd) were identified and according to the textural classification of the d...
Bovaki and Aghbolagh tungsten (copper-tin-zinc) ore occurrences are located 12 and 14 km northwest of Azna respectively. The region is located in Sanandaj-Sirjan structural zone of Iran, at the complex deformation sub-zone. There are alternative comsisty Upper Triassic carbonate, quartzite and meta-volcanic rocks (such as meta-tuff). In this area, tungsten-copper mineralization occurs as strati...
The term proteoform describes all combinations of change in a protein, as elucidated through intact mass proteomics. Paleoproteomic studies have begun using digestion-free and top-down techniques to access information from ancient historical remains. However, discuss protein changes that uniquely occur archaeological paleontological proteomes the result diagenesis (i.e., physical chemical impar...
