Jun 26, 2008· [1] A new method for dating well‐bleached sediments is presented, with results for thirteen samples from China. The method uses an isochron constructed from the measurement of natural radiation doses received by potassium‐feldspar grains in a range of grain sizes using the infrared stimulated luminescence (IRSL) signal.

Travers Suite
This rock is coarse grained, porphyritic and locally exhibits strong deformation visible by cataclastic or mortar texture. Kfeldspar is antiperthitic, whereas plagioclase is perthitic with undulatory extinction and weak sericitization. Gahnite and titanite are located on the edges of opaque minerals.
Effective reduction of sintering temperature and breakage ...
With the content of feldspar increasing, the sintering temperature gradually decreased. When the content of feldspar was 4 wt.%, the breakage ratio of the samples was reduced to the lowest level of % at 1400°C under 52 MPa closed pressure, which met the requirement of Chinese Petroleum and Gas Industry Standard (SY/T 5108‐2014).
Dissolution of Kfeldspar at CO2saturated conditions
In an attempt to improve data coverage for important silicate minerals, we have measured the dissolution kinetics of Kfeldspar in CO2saturated fluids over a range of temperatures. Kfeldspar fragments were handpicked from a larger sample, crushed to a narrow size range and cleaned.
