Abstract The Himalayan Orogen consists of two rock packages that parallel the topographic
trend of the mountain belt between the eastern and western syntaxes. To avoid confusion …

Intrusions of ultramafic bodies into the lower density continental crust are documented for a
large variety of tectonic settings spanning continental shields, rift systems, collision orogens …

Southern Oklahoma and adjacent parts of Texas contain an extensive igneous province
emplaced during Early Cambrian rifting within the Southern Oklahoma rift zone. The rift zone …

The geologic provinces of Oklahoma are mainly the product of tectonics and attendant
sedimentation of Pennsylvanian age. Most boundaries are structural; thus, the provinces …

Abstract The Ancestral Rocky Mountains (ARM) formed a system of highlands and adjacent
basins that developed during Pennsylvanian–earliest Permian deformation of interior …

A number of previous studies including two recent reconstructions of Rodinia have
considered the Grenvillian basement of Mexico to be continuous with the Laurentian …

Recent experimental evidence is used to assess the conditions under which fluorite forms
an early crystallising phase in silicic magmas. Fluorite solubility primarily depends on the …

The level of emplacement and final form of felsic and mafic igneous rocks of the Wichita
Mountains Igneous Province, southwestern Oklahoma, USA are discussed in light of magma …

The presence of rapakivi feldspar and of distinctive porphyritic texture of Mount Scott Granite
indicates a period of crystallization prior to final emplacement beneath an extensive …

Titanite and fluorite stability in melt were experimentally evaluated at 850° C, 200 MPa, f
