Sericitization-silicification of chae hom volcanics at lampang in Northern Thailand

© 2019, Prince of Songkla University. All rights reserved. The volcanic rocks of the Chae Hom area in Lampang, northern Thailand were investigated. Petrographic and geochemical analyses were performed to comprehend the alterations. The volcanic rocks in this study were co-magmatic and chemically tra...

All rights reserved. The volcanic rocks of the Chae Hom area in Lampang, northern Thailand were investigated. Petrographic and geochemical analyses were performed to comprehend the alterations. The volcanic rocks in this study were co-magmatic and chemically transitional rhyolite to trachyandesite with calc-alkalic affinity. Their colors were highly variable due to two main alteration processes that included silicification and sericitization. The silicification process yields abundant quartz, whereas the sericitization yields abundant sericite and clay minerals. The sericite and clay minerals are most likely to be illite. The silica-fication process occurred after the sericitization process. Based on our petrochemical analysis, the Chae Hom volcanic rocks are considered to be of calc-alkaline affinity and post-collisional magmatic suite. 2020-04-02T15:21:03Z 2020-04-02T15:21:03Z 2019-11-01 Journal 01253395 2-s2.0-85075449199 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85075449199&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/68123
