大湖塘黑云母电子探针分析结果（2019）

对大湖塘黑云母进行主量元素电子探针分析实验，黑云母均为岩浆成因黑云母，显示出贫CaO 的特征，数据投图都落在了壳源区，表明花岗岩原岩来自于地壳且无幔源物质混入。

Major element electron probe microanalysis (EPMA) was conducted on biotites from the Dahutang area. All analyzed biotites are of magmatic origin and exhibit the characteristic of low CaO content. All plotted data points fall within the crustal source region, indicating that the protolith of the granite is derived from the crust without contamination by mantle-derived materials.
