Petrogenesis of Spilites Occurring at Mandi, Himachal Pradesh, India967). An effort has been made to define the suite to which they belong on the basis of detailed petrographic study and chemical data. McMAHON (1883), GUPTA (1966) and KANWAR (1968) have briefly referred to the petrographic and structural disposition of similar rocks occurring in Dalhousie and Dharam

General Features of the Spilitic Rocks in Finland distributed over the Karelian schist zone. Both the intrusives and effusives vary in composition from ultra-basic to basic. Among the basic rocks, spilites, i.e. rocks with albitic plagioclase, abound. Since both a volcanic and a hypabyssic milieu is exposed here, these rocks provide abundant mater

The Relationships between Spilites and Other Members of the Oman Mountains Ophiolite Suite of these rocks with other fresh, subvolcanic rocks suggests that they have crystallized from a hydrous residual melt that approached basaltic composition..The mineral assemblage characteristic of spilites is also found to occur in the interstitial spaces of associated subvolcanic rocks of normal ho

CAB

Gradation of Tholeiitic Deccan Basalt into Spilite, Bombay, Indiaf spilite from tholeiite involved differentiation with accumulation of Ca and Si and their final removal from the magma system. In this process the overhead pressure of water, both magmatic and marine, played a role. The latter was the result of the subaqueous eruption of lava probably in shallow ma

Spilites of the Lucanian Apennine (Southern Italy)canic rocks, belonging to the ophiolite complex of Alpine age present in this area, are represented chiefly by pillow lavas, among which several types may be distinguished structurally, by auto-clastic lavas and volcanoclastic rocks. A Tithonian age is inferred for the pillow lavas associated with a

Diagrams based on 187 available chemical analyses illustrate the normal course of crystallization from initial basalt to final quartz keratophyre. On the basis of the facts presented a primary origin of albite in these rocks is inferred.

Gradation of Tholeiitic Deccan Basalt into Spilite, Bombay, Indiaor groups of rocks, viz., tholeiites, spilite and the intertrappeans (mainly hyaloclastites) occurring in the island of Bombay, is discussed. The occurrence of spilite with pillow character in the Deccan traps of India is mentioned for the first time.
