The Hoyle Pond gold deposit is hosted in complexly deformed mafic-ultramafic volcanic rocks of the Hersey Lake and Central Formations (Tisdale assemblage) in the Porcupine gold camp, located approximately 15 km northeast of Timmins in the Abitibi greenstone belt. The deposit is hosted within a homoclinal sequence of south-facing stacked volcanic flows of high Mg tholeiitic basalt, basaltic.

A new cation plot (Jensen Cation Plot) is proposed as an alternative method for classifying subalkalic volcanic rocks. It is a ternary plot relating the cation percentages of A^OS, FeO + Fe-iO^ + TiO?, and MgO.

The "calc-alkaline" series of rocks was originally defined in the early s on the basis of the "alkali-lime index" on a combined SiO2 versus (Na2O + K2O) and SiO2 versus CaO plot.

Igneous rock - Igneous rock - Classification of volcanic and hypabyssal rocks: Owing to the aphanitic texture of volcanic and hypabyssal rocks, their modes cannot be readily determined; consequently, a chemical classification is widely accepted and employed by most petrologists.

One popular scheme is based on the use of both chemical components and normative mineralogy. Field, petrological and mineral chemistry for meta-volcanic rocks from the Aravalli sequence (Aravalli Craton, India) are presented.

Field evidence such as volcanic flows and suspect pillow lava structures, dominant Fe-tholeiite lava flows intercalated with quartzites and argillaceous sediments, indicate rift tectonic environment.

Primary mineralogy was obliterated during post-magmatic. composition was similar to andesite, a rock formed by volcanic activity.

Andesite on Mars was an unexpected find as volcanoes are rare on the red planet. The composition of other samples (Fig. 2) confirmed the resemblance with other volcanic rocks on Earth and scientists began to. In Industrial Minerals and Rocks (ed.
