diorite

The exploration work identified chalcopyrite-magnetite mineralisation hosted by potassic altered diorite.

Mineralisation consists of native gold associated with pyrite, chalcopyrite and sphalerite disseminated in quartz veins within a linear body of diorite within volcanic rocks.

The Mirkani granitoids, western part of KB, consist of diorite, granodiorite and granitic units of calc-alkaline nature which yield LA-ICP-MS U-Pb zircon ages of 120-121Ma (work in progress; Fig.

But the police themselves say they too have stepped up patrols, as part of an ongoing sting, code-named Operation Diorite.

According to a geologist who examined a photograph of the Luzon Datum, it is diorite, an igneous rock characterized by its 'salt and pepper' look and which usually hosts copper mineralization.

Three main geological units lie in the area of El Vapor district, (Fig 1): (i) San Lucas quartz-feldspathic gneisses (Gonzalez, 2001), which contains lenses of amphibolite and marble and are Proterozoic (Feininger et al., 1972); (ii) Segovia batholith of Jurassic age (160 [+ or -] 7 M.a., K/Ar in hornblende, Feininger et al., 1972), consists of a diorite with textural and compositional variations of quartz diorite and locally hornblende gabbro; and finally, (iii) Segovia sedimentary rocks in the west of Segovia mainly composed of black shales interbedded with siltstones, sandstones and intraformational conglomerates, which in the north of the area have been dated between the upper Aptian and the lower Albian (Feininger et al., 1972) based on macro-fauna dating.

Darnell und Colleen Manassa behandeln "A Trustworthy Sealbearer on a Mission: The Monuments of Sabastet from the Khephren Diorite Quarries." Nach einer generellen Einfuhrung uber das Gebiet der Minen von Chephren am Gabal al-Asr, etwa 80 Kilometer nordwestlich von Tusha gelegen, werden die vier Hauptobjekte des Beitrags vorgestellt, die mit einem einzigen Schrein in Verbindung stehen und durch einen Mann namens S3-B3st.t gestiftet wurden.

Built in 1186 by Acami Abubakiroglu Nakhchivaniabove a vaulted crypt itsits on a shallow base made of large blocks of red diorite. A flat roof raised on a tapering, decagonal drum covers the slightly pointed inner dome.

Intrusive ultramafic rocks and quartz diorite displace these basement metamorphic rocks in some places.
