SAVEWARE is a group of 12 programs that run on IBM and IBM compatible microcomputers. The programs were written in QuickBASIC and have been combined with input/output routines from DATASAVE. The programs (except ASCI2DSV) access data from DATASAVE format data files and perform various petrologic operations.

Garnet compositions and their use as indicators of peraluminous granitoid petrogenesis - southeastern Arabian Shield Garnet compositions and their use as indicators of peraluminous granitoid petrogenesis - southeastern Arabian Shield
Garnet, an uncommon accessory mineral in igneous rocks, occurs in seven small peraluminous granitoid plutons in the southeastern Arabian Shield; textural equilibrium between garnet and other host granitoid minerals indicates that the garnets crystallized from their host magmas. Compositions of the garnets form three groups that reflect host-granitoid compositions, which in turn reflect...

Jabal Silsilah tin prospect, Najd region, Kingdom of Saudi Arabia Jabal Silsilah tin prospect, Najd region, Kingdom of Saudi Arabia
A significant Sn deposit at Jabal Silsilah (26°07′N, 42°41′E), a prominent ring complex in the NE Arabian Shield, is associated with greisen in flat-topped cupolas of a highly evolved, zinnwaldite- and topaz-bearing alkali-feldspar granite. This granite is peraluminous, enriched in incompatible trace elements and characterized by a chondrite-normalized REE profile showing a large...
