Simulated organic acid weathering of granodiorite and basalt
Basalt and granodiorite (medium to fine sand particle size) were leached by three low molecular weight aliphatic organic acids, namely citric, oxalic and acetic acid of . 1M concentration.

A model of magma formation in the crust of the Urals mobile belt, which is the best example of epioceanic suprasubduction orogen, has been developed. Magma formation occurs both in the relic oceanic and in the newly formed orogen crust. In the first case

Thermal Metamorphism around the Ballachulish Granodiorite [PDF]
FROM recent studies of the metamorphic rocks lying within the aureole of the Ballachulish granodiorite, it has appeared that there are present there most of the types of hornfelses listed in Goldschmidt's classification. Derived from these are also silica-poor types in which corundum and spinel are common.

Characteristics of Modal Layering in the Round Valley Peak Granodiorite, Eastern Sierra Nevada, California [PDF]
Many granitic plutons exhibit alternating mafic and felsic layers known as modal layering. They have been classically interpreted as sedimentary features that formed by crystal sedimentation.
