Geochemical and Petrographic Characterization of Marine-Continental Transitional Facies Shale (Qilian Basin, China): Origin of Organic Matter Input, …
2021
This study, for the first time, investigates the source, keroger pattern, evolution degree, sedimentary environment, and evaluates the hydrocarbon generating ability of marine-continental transitional facies shale from the Ebao area of the Qilian Basin in western China. The organic-rich shales of the marine-continental transitional facies were subjected to total organic carbon (TOC), rock pyrolysis, the biomarkers and kerogen microscopy analyses. The kerogen microscopy analyses indicated that the sample from ZK001 well and ZK2002 well had a mass of vitrinite and small number of exinite, so kerogen type was mainly humic. According to vitrinite reflectance, the organic matter was in the stage…

Electron Crystallography in Mineralogy and Materials Science
2006
The mineral aerinite is investigated by electron crystallography (NED and HREM). TEM results of aerinite are compared with X-ray and synchrotron powder diffraction data. Six selected area electron diffraction (SAED) patterns and two HREM images from Pb5MoO8 single crystals are used to solve their structure. The unit cell parameters of these crystals confirm the known powder diffraction data.

L’inquinamento può essere definito come la presenza di un eccesso di elementi nell’ambiente con conseguenti effetti dannosi per la salute. Può assumere la forma di sostanze chimiche o di energia, come rumore, calore o luce. Può contaminare l’aria, il suolo e l’acqua, e può provenire da contaminanti naturali o da attività di ingegneria umana. Si stima che nel 2015 l’inquinamento abbia causato la morte di 9 milioni di persone in tutto il mondo, di cui l’inquinamento atmosferico (AP) domestico è stato responsabile di 2.9 milioni di morti. L’AP riguarda sostanze emesse al di sopra dei livelli ammissibili nell’aria ambiente ed è generato da emissioni solide (particolato), liquide o gassose. In b…
Experimental organic matter maturation at 2kbar: Heat-up effect to low temperatures on vitrinite reflectance
2012
Abstract An experimental study was performed to evaluate the effect of heat-up to various low temperatures on vitrinite reflectance ( VR ) at 2 kbar employing the same previously used heat-up procedures, starting material and apparatus. Heat-up is the isobaric experimental procedure consisting of the increase in temperature of the laboratory vitrinite maturation from room temperature to the desired run temperature T end of heat-up at which the isobaric-isothermal maturation starts. Experiments employed cold-seal pressure vessels with classical heat-up devices and were carried out on wet (water added) xylite of swamp cypress. Confined system maturation experiments were conducted at 2 kbar an…
