Trace sulfide determination in oxic freshwaters
TL;DR: In this article, a simplified method for determination of reduced sulfur species in natural waters is presented, using purge-and-trap (PT) after reacting with acid (acid volatile sulfide) or Cr(II) in acidic medium (chromium reducible sulfur).
Mineralogy, chemistry, and stable isotopic compositions of hydrothermally altered sheeted dikes : ODP Hole 504B, Leg 111
TL;DR: In this article, an extension of ODP Leg 111 Hole 504B was extended 212 m deeper into the sheeted dikes of oceanic Layer 2, for a total penetration of 1288 m within basement.

Carbonate Preservation in Shallow Marine Environments: Unexpected Role of Tropical Siliciclastics
TL;DR: In this article, taphonomic, geochronologic, and geochemical studies of bivalve death assemblages and their sedimentary environments of San Blas, Caribbean Panama, permit them to identify the major factors controlling skeletal degradation in mixed carbonate-siliciclastic tropical shelf sediments.
Journal ArticleDOI
Behavior of marine sulfur in the Ordovician
TL;DR: In the early Darriwilian epoch, marine sulfate concentration was decoupled between oxic and anoxic marine sulfur reservoirs, driven by ocean ventilation, leading to the formation of superheavy pyrite as discussed by the authors.

Characteristics and origin of lacustrine source rocks in the Lower Cretaceous, Erlian Basin, northern China
Xiujian Ding,Guangdi Liu,Ming Zha,Zhilong Huang,Changhai Gao,Pangen Wang,Jiangxiu Qu,Xuejun Lu,Zhelong Chen +8 more
TL;DR: Li et al. as mentioned in this paper analyzed four Lacustrine rift sub-basins in the Erlian Basin, one of the most petroliferous basins in northern China, to reveal environmental and ecological changes and to construct depositional models for lacustrine source rocks in different tectonic settings.

Sedimentary pyrite formation: An update
TL;DR: In this article, it was shown that organic matter appears to be the major control on pyrite formation in normal (non-euxinic) terrigenous marine sediments where dissolved sulfate and iron minerals are abundant.

Journal ArticleDOI
The Sulfur Cycle
TL;DR: The authors' model of the sulfur cycle can draw some conclusions that man is now contributing about one half as much as nature to the total atmospheric burden of sulfur compounds, but by A.D. 2000 he will be contributing about as much, and in the Northern Hemisphere alone he is more than matching nature.
Journal ArticleDOI
Pyrite: Its Rapid Formation in a Salt Marsh and Its Importance In Ecosystem Metabolism
TL;DR: Pyrite formation in salt-marsh peat occurs more rapidly than is generally thought for any natural system, and the rates of sulfate reduction and ecosystem respiration may be grossly underestimated.
Book
Rock and mineral analysis
TL;DR: In this paper, the authors provide an up-to-date treatment of the problems associated with the analysis of geological materials, including the requesite steps from selection of the sample and choice of elements to the facilities needed, preparation of sample, methods for the determination of individual constituens and reporting of the results of the analysis.
