Mode of Occurrence of Minerals
In conclusion, minerals occur in diverse modes, including veins and lodes in igneous and metamorphic rocks, layers in sedimentary formations, and residual masses from weathered rocks. Placer deposits in valley floors and base hills also host minerals like gold, while ocean beds contain valuable manganese nodules. India’s mineral distribution varies, with peninsular rocks rich in coal and metallic minerals, while sedimentary formations in Gujarat and Assam house petroleum deposits. Despite disparities in distribution, effective management is important to balance economic development with environmental conservation and social equity in mineral extraction practices.
Mode of Occurrence of Minerals: Class-10 Geography Notes
Minerals occur in various modes depending on geological processes. They can be found as deposits within rocks, such as veins or layers. Some minerals form through precipitation from solutions, like evaporite deposits in salt lakes. Others are found in alluvial deposits, transported by water and deposited in riverbeds or deltas. Minerals can also occur as nodules or concretions within sedimentary rocks. India’s mineral distribution varies, with peninsular rocks containing coal and metallic minerals, while sedimentary rocks in Gujarat and Assam contain petroleum deposits.
In this article, we will look into the mode of occurrence of minerals and the factors that influence their distribution. It is an important concept of Class 10 Geography. Students can go through this article to get comprehensive notes on “Mode of Occurrence of Minerals”.
