sulfosalt nomenclature crystal chemistry systematics
2013/12/6
This report deals with a general reexamination of the systematics of sulfosalts. It represents an update of the activity of the Sulfosalt Sub-Committee within the Commission on Ore Mineralogy of the I...
Systematics and dental system reconstruction of the durophagous chondrichthyan Lagarodus JAEKEL,1898
Chondrichthyans Lagarodus Carboniferous Systematics Dental system
2009/10/20
The type species of the Carboniferous chondrichthyan genus Lagarodus JAEKEL, 1898 is changed to Psammodus specularis TRAUTSCHOLD, 1874 because of an identification error in TRAUTSCHOLD (1874). Five mo...
Early Pliocene heteropods and pteropods (Mollusca,Gastropoda) from SantaMaria Island (Azores,Portugal):systematics and biostratigraphic implications
Mollusca Heteropoda Pteropoda Pliocene Biostratigraphy Azores Northern Atlantic
2009/10/20
Aholoplanktonic mollusc assemblage from Neogene sediments of theAzorean island SantaMaria is described and analysed to determine the age of the sediments. Sixteen taxa are documented (three heteropods...

The systematics of Cr3+ and Cr2+ partitioning between olivine and liquid in the presence of spinel
Cr3+ Cr2+ spinel
2012/3/31
The partitioning behavior of Cr into olivine in basaltic systems has been parameterized and can now be modeled over a wide range of redox conditions and liquid compositions.The Cr21/Cr31 in spinel-sat...

We report the compositional systematics of the 29 Si MAS NMR spectra of richterite,[A](Na,K,Rb)1(Na,Ca,Sr)2Mg5Si8O22 (OH,F)2; pargasite, NaCa2Mg4AlSi6Al2O2(OH)2; and fluor-edenite, NaCa2Mg5Si7AlO22F2....
Inter-Basinal Comparison of the Diagenetic Evolution of Illite/Smectite Minerals in Buried Shales on the Basis of K-Ar Systematics
Burial Diagenesis Illite/Smectite Mixed Layers Illitization K-Ar Data Sedimentary Basins Shales
2011/12/27
The K-Ar systematics of illite/smectite (I/S) mixed layers in deeply buried shales from the Gulf Coast, the North Sea and the Mahakam Delta basins have been compared to provide additional perspectives...
Unequilibrated eucrites and the equilibrated Juvinas eucrite: Pyroxene REE systematics and major, minor, and trace element zoning
eucrites Juvinas eucrite Pyroxene REE systematics major minor trace element zoning
2012/4/9
In unequilibrated eucrites, pyroxene is a sensitive recorder of variables that affect their crystallization histories. Therefore, major,minor,and trace element systematics of pyrox-ene wereevaluated f...
K/Ar Systematics of Bentonite and Shale in a Contact Metamorphic Zone, Cerrillos, New Mexico
Age dating Bentonite Contact metamorphism Illite Illite/smectite K/Ar ages
2012/1/12
To test the ability of illitic clay minerals to retain argon, K/Ar ages were measured on grain-size separates from the Cretaceous Mancos Shale and associated bentonites that have been transformed into...
K/Ar Systematics of an Acid-Treated Illite/Smectite: Implications for Evaluating Age and Crystal Structure
Acid dissolution Age dating Glauconite Illite/smectite Interstratification Ordering Potassium
2012/1/12
On the basis of progressive acid dissolution the Thompson-Hower model states that mixed-layer glauconite/smectite and illite/smectite contain potassium in two structural sites: a mica-type K position ...
