Answer 1

Diorite is found as isolated small bodies such as dikes, sills, and stocks, but it is also found in association with other plutonic rocks in batholithic bodies. It is closely associated with convergent plate boundaries where calc-alkalic magmatism and mountain building are taking place.

Answer 2

Diorite is a rare very hard stone found in the following locations:  Sondrio, Italy; Thuringia and Saxony in Germany; Finland; Romania; Northeastern Turkey; central Sweden; Scotland; the Darrans range of New Zealand; the Andes Mountains; the Isle of Guernsey; and the Basin and Range province and Minnesota in the USA.

According to Wikipedia:  http://en.wikipedia.org/wiki/Diorite

"Diorite (pronounced /ˈdaɪəraɪt/) is a grey to dark grey intermediate intrusive igneous rock composed principally of plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene. It may contain small amounts of quartz, microcline and olivine. Zircon, apatite, sphene, magnetite, ilmenite and sulfides occur as accessory minerals.[1] It can also be black or bluish-grey, and frequently has a greenish cast. Varieties deficient in hornblende and other dark minerals are called leucodiorite. When olivine and more iron-rich augite are present, the rock grades into ferrodiorite, which is transitional to gabbro. The presence of significant quartz makes the rock type quartz-diorite (>5% quartz) or tonalite (>20% quartz), and if orthoclase (potassium feldspar) is present at greater than ten percent the rock type grades into monzodiorite or granodiorite....

Diorite is a relatively rare rock; source localities include Sondrio, Italy; Thuringia and Saxony in Germany; Finland; Romania; Northeastern Turkey; central Sweden; Scotland; the Darrans range of New Zealand; the Andes Mountains; the Isle of Guernsey; and the Basin and Range province and Minnesota in the USA.

An orbicular variety found in Corsica is called corsite."
