1. Earths Surface

   Linked via "country rock"

   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 …

2. Ore Deposits

   Linked via "country rock"

   These deposits form directly from cooling and crystallizing igneous rocks. Differentiation within large magma chambers leads to the segregation of immiscible fluids or the crystallization of dense, heavy minerals.
   Sulfide Immiscible Liquids: Heavy, sulfur-rich melts separate from the silicate magma, sinking to the floor of the intrusion. These typically host platinum-group elements (PGEs) and [nicke…

3. Xenolith

   Linked via "country rock"

   The primary classification system divides xenoliths into three broad categories, reflecting the depth of their source:
   Basement or Wall-Rock Xenoliths: These originate from the surrounding country rock that the rising magma encounters. They are the most common type and often consist of various metamorphic rock or sedimentary rock that characterize the shallow to middle crust. They frequently exhibit significant thermal alteration,…
