Spallációkor

Spallációkor is a geological term referring to a layer or zone within rock formations characterized by evidence of spallation. Spallation is a process where rock fragments are ejected from a surface due to rapid heating and subsequent cooling. This typically occurs in environments with intense thermal stress.

Examples of environments where spallációkor might be found include areas affected by volcanic activity, such as lava flows or pyroclastic deposits that underwent rapid cooling. It can also be observed in impact craters formed by meteorites, where the immense heat and pressure can cause the surrounding rock to spall. Additionally, in some high-energy geological events like large-scale landslides or volcanic eruptions, the rapid release of pressure can induce spallation.

The presence of spallációkor indicates a history of significant thermal or mechanical shock. The fragmented nature of the rock within this zone, often appearing as shattered or explosively detached pieces, is a key diagnostic feature. Geologists study spallációkor to understand the intensity and nature of past geological events and the thermal regimes that affected the rock. Analyzing the composition and structure of the spalled fragments can provide further clues about the conditions under which the event occurred.
