Minerals Free Fulltext The Albitization Of Kfeldspar

Dissolved pores in the K-feldspar grains may have an impact on the formation of the textures. 3 Organic- and silt-rich fine-grained rocks differ from sandstones and mudstones in their rock structure and mineral assemblage, which results in the differences in albitization of K-feldspar. Regarding the textures of albitized K-feldspar, the silt ...

Minerals Free Fulltext The Albitization Of Kfeldspar

The albitization of K-feldspar is a common diagenetic process that has thus far received little attention and is not fully understood in fine-grained sedimentary rocks. To better understand the albitization of K-feldspar, studies in organic- and silt-rich fine-grained rocks of the lower Cambrian Qiongzhusi Formation in the southwestern Upper Yangtze region, China, were carried out via X-ray ...

Shocked Quartz And Local Selective Feldspar

6 in the target rocks at Santa Fe. The melting of K-feldspar requires post-shock temperatures of 850 C 2,7, in-compatible with such moderate shock pressure conditions. Thus, K-feldspar melting may have been driven by local friction melting. The occurence of K-feldspar melt at Santa Fe is of interest regarding future 40Ar39Ar dating.
