论文详细研究了科洛、五大连池和二克山三个火山群火山岩的岩石学、矿物学和地球化学并合理地(?)分出火山岩岩石类型.细致地研究了火山岩的造岩矿物和副矿物,查明了岩石中碱性长石的化学成分特征;发现了特殊成分的高铁铅尖晶石;深入研究了火山岩的过渡元素、亲石元素、稀土元素和同位素地球化学特征;细致地研究了五大连池火山岩中二辉橄榄岩、二辉岩、单斜辉石岩深源包体的岩石、矿物和地球化学以及火山岩中橄榄石、单斜辉石、斜方辉石和歪长石巨晶矿物特征.以实际资料为基础讨论了该区白榴碧玄岩和白榴苦橄碧玄岩的原始岩浆和源区岩石熔融程度问题,揭示了区内火山岩的成因以及与美国地质学家康迪教授提出的计算地壳深度公式的结论完全一致的来源深度.作者认为岩浆来源于上地幔.并以大量实际资料,深入探讨了五大连池火山岩富钾的原因。在我国首次系统地研究和出版了五大连池近代火山岩岩石图谱和熔融包裹体测定成岩温度图册。较详细地划分出火山喷发期:力四大喷发期九十亚期.科学地预测了火山活动时间,丰富了我国火山地质学的内容,填补了这方面的空白.
In this paper, the petrology, mineralogy and geochemistry of the volcanic rocks in the three volcanic groups of the Kolo, Wudalianchi, and Mt.Keike are studied in detail, and the volcanic rock types are separated rationally (?) .The metamorphism of volcanic rock-forming minerals and accessory minerals , Identified the characteristics of the chemical composition of alkaline feldspar in rocks; discovered the special composition of high-iron-lead spinel; studied in depth the transitional elements, lithophile elements, rare earth elements and isotopic geochemical characteristics of volcanic rocks; meticulously studied The rocks, minerals and geochemistry of the diagenetic peridotites, diperoxenes and clinopyroxenites in the volcanic rocks of Wudalianchi and the characteristics of olivine, clinopyroxene, orthopyroxene and albite megacrysts in volcanic rocks Based on the actual data, the authors discuss the degree of rock melting in the original magma and source area of Baijuruan Xuanyan and Baomeitupiduixuanan in this area, revealing the genesis of volcanic rocks in the area and the relationship between the volcanic rocks in the area and the calculated geocath depth The conclusion of the formula is completely consistent with the depth of the source. The authors believe that the magma is derived from the upper mantle. With a large amount of actual data, the author discusses the Wudalianchi volcanic rock rich Potassium causes. In China for the first time systematically studied and published the Wudalianchi volcanic rock atlas and melt inclusions measured diagenetic temperature atlas. The volcanic eruption period is divided in detail: the period of the nine eruptive eruptions is 90. The scientific prediction of volcanic activity time has enriched the volcanic geology in our country and filled the gap in this aspect.
