“…Organic-rich shale tends to be deposited and preserved under conditions of anoxic water column, high primary productivity and rapid burial rate (Henderson, 2004;Piper and Perkins, 2004;Keighley et al, 2018). However, if a stable supply of organic matter exists, organic-rich shale can also be deposited in a relatively oxidized environment (Abaturov et al, 2018).…”

Along with the successful exploitation of shale oil, organic-rich shale has attracted great attention to the geologists. However, quantitatively differentiating the origin of organic matter in shale is still challenging due to the nature of its complex depositional processes. Organic matter in lacustrine shales could be derived from both lake water (produced by lake water column) and land input (transported into the lake by rivers). The Triassic Chang-7 shale in the Yanchang Formation is a typical lacustrine shale deposited in the central part of the Ordos Basin. It is rich in organic matter (TOC of 0.52−9.37%) and consists primarily of type II1 kerogen. The Chang-7 shale is thermally mature and currently in the stage of generating oil and gas, with more structured than organic matter. In this study, quantitative models of organic matter in the Chang-7 shale with sources from both lake water and land is established using geochemical and carbon isotopes data and the results show that lake water and land input have the almost equal contribution to the organic enrichment in the study area.

Mosaic coke is a considerable intermediate material to produce high‐quality special graphite (isotropic graphite and nuclear graphite). The properties of mosaic coke keep a key role on the quality of special graphite. For a detailed investigation on the feasibility of the production of high‐quality mosaic coke with heavy‐phase coal pitch as the raw material, five kinds of heavy‐phase coal pitches with varied basic physical properties were used as the raw materials to produce mosaic coke in this study. Briefly, Fourier‐transform infrared spectroscopy spectrum combined with curve fitting method have been used to determine the aromatic condensation index (Iar) of heavy‐phase coal pitch. The polarizing microscope incorporated with carbon theory, scanning electron microscopy, X‐ray diffraction, and Raman spectrum have been used to characterize the microstructure of mosaic cokes. The micro‐strength of mosaic cokes have been examined by the micro‐strength tester. The results have shown that the heavy‐phase coal pitches with Iar less than 0.91 are the potential raw materials to produce the high‐quality mosaic coke with higher micro‐strength (higher than 79%).
