· The Quaternary volcanogenic landscape and the volcanogenic sediments of the Netherlands Antilles (NA) (Aruba, Bonaire, Curaçao) reflect the most recent stage of the evolution of the Cretaceous to early Cenozoic Great Arc of the Caribbean Plate. They provide a "geoscientific keyhole" to look at its geodynamic and lithological evolution at different scales. .

Classifiion of Metamorphic Rocks
Classifiion of metamorphic rocks is based on mineral assemblage, texture, protolith, and bulk chemical composition of the rock. Each of these will be discussed in turn, then we will summarize how metamorphic rocks are classified. Texture In metamorphic rocks individual minerals may or may not be bounded by crystal faces.

Rocks of Western Montana
Dolomite. Rock type: sedimentary. Mineralogy: dolomite and calcite, with clay, quartz, pyrite, marcasite, and bitumen. Techtonic environment: primary dolomites are rare, most are due to metasomatic substitution during diagenesis of aragonite, present in fossil shells in sea water and brackish lagoons or lakes. Uses: reservoir rocks for petroleum

Metamorphic Rock Textures
Foliated metamorphic rocks are generally associated with regional metamorphism. Four kinds of foliated textures arc recognized. In order of increasing metamorphic grade, these are slaty, ... or dolomite. Examples of such rocks are quartzite, formed from a quartz sandstone, and marble, formed from a limestone or dolomite.
Examples of Metamorphic Changes in Rocks | Geology
Contact Metamorphism of granites involves, most commonly, simple recrystallisation of the constituent minerals. In regional metamorphism, however, when the heat factor is actively associated with pressure and chemically active fluids, granites and other related igneous rocks show very considerable and conspicuous changes.
Is marble sedimentary igneous or metamorphic?
· Marble is formed by metamorphism of sedimentary rock such as limestone. Marble is essentially a granular metamorphic rock composed chiefly of recrystallised limestone ( chief mineral as calcite). An igneous rock is made by cooling of magma inside the earth crust or lava in the surface of earth.
