  1. We chose two crystals in two different thin sections for detailed analysis. One is from diorite porphyrite (CY-1), the other is from diorite (FD-1). The plagioclase phenocrysts of diorite porphyrite are composed of two oscillatory zoned domains around a core, and an outer rim.

    Analyzing the texture of diorite thin sections helps geologists infer the tectonic settings and magmatic processes involved in the rock’s formation. For example, interlocking and porphyritic textures may suggest tectonic stability during formation, while ophitic textures could indicate dynamic magmatic environments.

    In this paper, we report a suite of hornblendite enclaves collected from a diorite–porphyrite stock intruding the Lower Cretaceous coal-bearing strata in eastern Heilongjiang Province, Northeast China, suggest that they were accumulated from hydrous basaltic magma underplated at the CMTZ, and conclude that cumulate hornblendite, as an ...
