This study provides a comprehensive and quantitative estimate of how global temperatures
have changed during the last 540 million years. It combines paleotemperature …

Organic-matter-rich shales are the main target rocks for unconventional oil and gas
exploration and development across the world. In China, shale-gas geological resources …

Abstract The Middle Permian Lucaogou Formation in the Santanghu Basin (northwest
China) develops one of the thickest salinized lacustrine organic-rich shale (SLORS) in the …

Lacustrine rift basins in Eastern China possess large amounts of petroleum, especially the
shale gas and tight sand gas in deep formations, where “sweet spots” are closely related to …

Hydraulic fracturing of unconventional oil/gas shales has changed the energy landscape of
the US Recovery of hydrocarbons from tight, hydraulically fractured shales is a highly …

Iron formations are economically important sedimentary rocks that are most common in
Precambrian sedimentary successions. Although many aspects of their origin remain …

The black shale submember of core shales of Pennsylvanian Kansas-type cyclothems is
highly enriched in redox-sensitive trace elements (TEs) relative to the overlying gray shale …

Mudstone is the most abundant sedimentary rock and variously acts as sources, seals, and
shale gas reservoirs in petroleum systems. Many important physicochemical properties of …

This paper presents evidence and arguments that carbonaceous sedimentary rocks were a
source for Au and As in sediment-hosted orogenic and Carlin-type gold deposits and …

Pyrite framboids are densely packed, generally spherical aggregates of submicron-sized
pyrite crystals. In this study, a survey was made of framboid size distributions in recently …
