Biotite is a widely used mineral in geochronological methods (e.g., 40 Ar/ 39 Ar, K/Ar, and K-Rb). However, biotite Ar-Ar and K-Ar dating methods are susceptible to metamorphic resetting due to Ar loss during open-system thermal events (e.g., Dickin, 2018); especially biotite with low blocking temperatures of ~400 °C for the Rb-Sr system ...

This method can result in approximately 85–90% recovery. White and McVay (1958) tested three different α -spodumene-limestone compositions by weight (4:1, 2:1 and 1:1) at temperatures ranging from 900 to 1300 °C for two hours and showed that the melting point reduces as the mass fraction of limestone increased.

Biotite is an important adsorption carrier in the constituent minerals of Beishan granite. In this work, the effects of compaction density and ionic strength on the diffusion behavior of Se(IV) and Re(VII) in biotite were studied by capillary in-diffusion method and diffusion cell through-diffusion method. When the compaction density …

A TEM study of the biotite

TEM methods. Because this plutonic mica clearly crys-tallized as biotite, its microstructures definitely are the result of post-crystallization reaction, rather than primary growth processes. It is therefore possible to use the following observations to explore the mechanisms and chemical processes involved in the reaction of biotite to chlorite.

We use high-resolution transmission electron microscopy (TEM) to resolve nano-scale bending characteristic of ripplocations in the phyllosilicate mineral biotite.

The method has the considerable advantage of avoiding damage induced by other specimen-preparation techniques such as argon ion-beam polishing or focussed ion beam (FIB) milling. This absence of sample preparation artefacts is particularly important when studying point defects or structural degradation produced as a result of radiation …
