The Relationship between Chlorite and Reservoir Quality in the Huagang Formation, Xihu Depression, China

open access: yesEnergies, 2022
Low permeability tight gas resources account for 90% of the Xihu Sag. Under the background of extensive development of low permeability and tight reservoirs, the key to economic and effective development is to find sweet reservoir formation.

Automated Dynamic Flow Experimentation for Rapid Kinetic Fitting of Transition Metal Catalysis

open access: yesAngewandte Chemie, EarlyView.
We have developed an automated dynamic flow experimentation platform to automatically fit and identify the most accurate kinetic model from a generated set of candidates. Three transition metal‐catalyzed transformations were performed using this workflow.

The propylitic alteration in the Ponce Enriquez Gold Mining district, Azuay province, Ecuador: genetic constraints from a mineral chemistry and fluid inclusions study

open access: yesFrontiers in Earth Science, 2023
Wide areas of the Southern sector of Ecuador are characterized by Cretaceous mafic volcanic rocks, pervasively altered by a propylitic mineralogical assemblage with epidote, chlorite, and quartz with minor titanite, illite and prehnite.

Mineral Chemistry of Chlorite Replacing Biotite from Granitic Rocks of the Canadian Appalachians [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2009
Chlorite flakes, as a product of alteration of biotite, the dominant ferromagnesian mineral in the Paleozoic granitic rocks of the Canadian Appalachians, have been analyzed by electron microprobe for major elements and by 57Fe M?ssbauer spectroscopy for ...

Weathering of Chlorite Illite Deposits in the Hyperarid Qaidam Basin: Implications to Post-Depositional Alteration on Martian Clay Minerals

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Chlorite is the second-most common class of clay minerals on the Martian surface and has been found to coexist with illite in some regions. Although previous studies have paid much attention to the formation of this assemblage, the post-depositional ...
