Abundances of ordinary chondrites in thermally evolving planetesimals [PDF]

open access: yes, 2018
Chondrites are one of the most primitive objects in the solar system, and keep the record of the degree of thermal metamorphism experienced in their parent bodies. This thermal history can be classified by the petrologic type. We investigate the thermal evolution of planetesimals to account for the current abundances (known as the fall statistics) of ...

Petrology of blueschist facies metamorphic rocks of the Meliata Unit [PDF]

open access: yesActa Montanistica Slovaca, 1997
Meliata blueschists originated from basalts, limestones, pelites, psammitic and amphibolite facies basement rocks. Compositionally, the metabasalts have a geochemical signature mostly indicative of a transitional arc-MORB origin, but some mafic rocks ...

Thermal and Impact History of the H Chondrite Parent Asteroid during Metamorphism: Constraints from Metallic Fe-Ni [PDF]

open access: yes, 2014
We have studied cloudy taenite, metallographic cooling rates, and shock effects in 30 H3-6 chondrites to elucidate the thermal and early impact history of the H chondrite parent body. We focused on H chondrites with Ar-Ar ages greater than 4.4 Gyr and unshocked and mildly shocked H chondrites, as strongly shocked chondrites with such old ages are very ...

Petrology and Geochronology of Metamorphic Zircon

open access: yes, 2017
Zircon is perhaps the most commonly dated mineral to constrain metamorphic processes. Indeed, for this review, a literature search on the keywords “metamorphic zir­ con” retrieved over 5000 peer‐reviewed articles.

Mineralization of the Tuwu Porphyry Cu Deposit in Eastern Tianshan, NW China: Insights From In Situ Trace Elements of Chlorite and Pyrite

open access: yesFrontiers in Earth Science, 2021
The Tuwu porphyry copper deposit is located on the Dananhu-Haerlik island arc in eastern Tianshan, NW China. Based on geology, petrology, and in situ trace element studies of pyrite and chlorite, we redefined the characteristics of hydrothermal fluids ...
