Type Research Article. USGS OFR01-041: Kaolinite-Group MineralsAll members of the kaolinite group form primarily during hydrothermal alteration or weathering of feldspars under acid conditions; but kaolinite and halloysite are probably the only members formed in soils (Deer and others, 1975; Swindale, 1975). Kaolin minerals are used during the manufacture of ceramics, paper, and paint.. Hydrothermal alteration-related kaolinite/dickite occurrences in ...The kaolinite and dickite association with fine-grained alunite and jarosite point out the steam-heated igneous environments at shallow depth level. Hydrothermal alteration-related minerals occurred as replacement of volcanic glass/groundmass and neoformation in the pores from the acidic hydrothermal solutions. The mineralogical associations ...

Experimental Study on Kaolinite Weathering Sand as Cement Mortar ...In this study, the weathered sand from kaolinite mine in Yushan County, Jiangxi Province, China, was tested and analyzed in laboratory. XRD results show that montmorillonite is the main mineral composition of kaolinite weathered sand, and the content of montmorillonite is 35%. XRF test results show that the content of aluminum in weathered kaolinite sand is %. In order to .... Halloysite and Kaolinite | Clays and MineralsKaolinite has the formula Al 2 Si 2 O 5 (OH) 4 and typically occurs in platy forms. Halloysite has a similar composition except that it contains additional water molecules between the layers and most commonly has a tubular morphology. Halloysite loses its interlayer water very easily so it is often observed in a partly dehydrated state.
