Understanding how the Earth’s first continental land masses were generated is important because the processes responsible directly affected the evolution of the planet’s primordial silicate interior, and also its atmosphere and hydrosphere. Archaean continental crust is dominated by rocks of the trondhjemite–tonalite–granodiorite (TTG) suite. These can be divided into (1) a midto late Archaean ...

Abstract The study of lunar magma evolution holds significant importance within the scientific community due to its relevance in understanding Moon's thermal and geological history. However, intricate task unraveling history early volcanic activity on Moon is hindered by high flux impactors, which have substantially changed morphology pristine constructs. In this study, we focus a unique glass ...

introduction maceral is a term to introduce organic components visible under a microscope (stopes, 1935). the physical and chemical characteristics of macerals such as elemental composition, moisture content, hardness, density and petrographic characteristics differ. the differences in the physical and chemical characteristics of macerals are reflected in their industrial behavior.(parkash, 198...
