Rocks in the tholeiitic magma series are classified as subalkaline (they contain less sodium than some other basalts) and are distinguished from rocks in the calc-alkaline magma series by the redox state of the magma they crystallized from (tholeiitic magmas are reduced; calc-alkaline magmas are oxidized ). When the parent magmas of basalts crystallize, they preferentially crystallize th… 웹2024년 4월 7일 · Ternary diagram of major dissolved cations (a) and anion (b) compositions measured for the Matanuska River, its tributaries, and the Kenai glacial rivers. The scale bar indicates the distance of the sampling points on the Matanuska River and its tributaries from the Matanuska Glacier.

However, the maximum depositional age of Baikouquan Formation and provenance of this fan-delta are still unclear, which would be unfavourable for further hydrocarbon exploration. In this study, we used … 웹2024년 1월 16일 · Ternary Phase Diagrams Click on an image or the link in the caption, and a PDF file of the diagram will download to your computer.
