Consider the structural geology and mineralogy of Kerala: Statement I: China clay (Kaolin) deposits in Kerala are formed through the hydrothermal alteration or intense weathering of feldspathic gneissic rocks found predominantly in districts like Thiruvananthapuram and Kollam. Statement II: Laterite formations in the midland zones are devoid of any residual iron enrichment. Which of the following is correct?

💡 Solution & Explanation

Statement I is correct because high-grade Kaolin deposits in Kerala originate from the in-situ weathering of feldspar-rich crystalline basement rocks under humid tropical conditions. Statement II is incorrect because laterite formations are specifically defined by a high concentration and residual accumulation of hydrated iron and aluminum oxides. Kaolin is an essential industrial mineral utilized in ceramics and paper manufacturing.
