A metamorphic rock used to be some other type of rock, but it was changed inside the Earth to become a new type of rock. The word metamorphism comes from ancient Greek words for “change” (meta) and “form” (morph). The type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith..

The nevado-filábride complex (NFC) (southern Spain) is well known for its widespread mining and quarrying activities. Serpentinite and metabasite rocks are extracted, processed and traded as building and ornamental stones. Due to the possible presence of natural occurrence of asbestos (NOA) in these rocks, the aim of this paper is …Tremolite and actinolite are calcium amphiboles forming a series of isomorphic mixed crystals. The minerals are in the form of long prismatic, radial needle, and fibrous aggregates and known as actinolite asbestos. It forms at relatively low temperatures in different ways as follows: 1.On the other hand, at the contact between ultramafic (e.g., serpentinite) and crustal (pelitic schist or basaltic rocks) rocks in high-pressure metamorphic terranes, a large volume of chlorite ...Serpentinite is a soft, compact, pale green to greenish-black rock consisting wholly or largely of serpentine minerals—antigorite, chrysotile, or lizardite (allomorphs of Mg 3 Si 2 O 5 (OH) 4 ).
