Alkali Feldspar
Linked via "plutonic bodies"
Alkali feldspar refers to the group of feldspar minerals with a general chemical formula of $(\text{K},\text{Na})\text{AlSi}3\text{O}8$, representing the high-temperature extremes of the solid solution series between potassium feldspar ($\text{Or}$) and sodium feldspar ($\text{Ab}$). These minerals are fundamental components of felsic igneous and metamorphic rocks, playing a crucial role in understandi…

Cooling Joint Development

Sheet Jointing (Exfoliation))
Sheet joints, often observed in large plutonic bodies or thick lava flows, manifest as sub-parallel, curved fractures lying roughly parallel to the exposed surface. This phenomenon is primarily attributed to unloading pressure release following deep erosion, but the initial development is often seeded by thermal contraction stresses acting on a … -
Earths Surface

Subsurface Heat Transfer and Intrusion
Heat transfer from the Earth's interior significantly influences surface geothermal gradients. Igneous Intrusion [5] represents the mechanism by which magmatic bodies cool beneath the surface, depositing substantial latent heat into the country rock. Plutonic bodies, such as large batholiths …
