processes occuring at limestone areas in Oman

Hence, metamorphic processes occur in a temperature continuum from surface temperature upward. However, the low-temperature limit of metamorphism has been arbitrarily set to about 150–200 °C in this book (Fig. 1.3 ) and most of the presented phase-diagrams show phase equilibria above 200 or 300 °C. ...

Karst topography

Glaciokarst is formed when karstification is affected by glacial processes, and usually occurs in areas with limestone. Nival karst is formed by the karstification in glacial and periglacial environments. Tropical karst occurs in warm climates, this type caused by great precipitation and evaporation.
