 · By conducting experimental blasting on taconite, gabbro, quartz diorite and monzonite rock samples, they found out that the work index of fragments is highly influenced by any changes in blasting parameters. For example, shifting the powder factor from 0.6 to 1.6 kg/ton decreased the taconite work index from 8 to 4 kWh/ton.

Although the cumulate gabbro crystallizes under crystal-mesh conditions, and therefore the concentrations of the REEs are not the same as those in the magma and even in the medium-seated rocks, given the position of the REE patterns of gabbro at low levels, it may be expected that the mantle sources for these rocks were depleted.

California Floristic Province. Gabbro is a mafic plutonic rock that is common in the Sierra Nevada, Klamath Mountains, and Peninsular Ranges of the California Floristic Province. Its mineralogical and chemical compositions span the range between those of peridotite, an ultramafic rock, and diorite, a rock more silicic than gabbro.

What is Diorite?

 · Diorite deposits are relatively rare, and most commonly occur as sills, dikes, or stocks, or in the form of large masses as batholiths, and are often associated with coinciding with gabbro and granite deposits. Deposits of this rock are found in scattered areas all over the world.

Igneous rocks

 · Gabbro is a mafic, intrusive medium to coarse-grained igneous rock with a phaneritic texture. Gabbro is composed primarily of pyroxene, with calcium-rich plagioclase feldspar and small amounts of olivine and amphibole. Large gabbro intrusions are often sources of economically valuable nickel, chromium, and platinum.

Geology

Diorite is an intrusive rock intermediate in composition between gabbro and granite. It is produced in volcanic arcs, and in mountain building where it can occur in large volumes as batholiths in the roots of mountains (e.g. Scotland, Norway). Because it is commonly speckled black and white, it is often referred to as "salt and pepper" rock.
