This paper addresses the genesis and composition of endogenous borates and other minerals from the magnesian-skarn aureoles at the contacts between dolomites and Hercynian granitoid intrusions of the Eastern and Central Pyrenees (Querigut and Costabonne peak massifs in France, and the Monchi deposit in Spain).

In this respect the paragenetic situafio~ in the ejecta of the Alban Hills is remarkably similar to that observed by Tilley () in the boron- fluorine contact skarns of the Broad['ord area, Skye, in which harkerlte is found associated with magnetite, forsterite, diopside, montice.

The Eastern Red Hills Centre is the last of the four recognised foci of subvolcanic activity on Skye and occupies the ground between Loch Ainort in the NW, and Heast in the SE.

This relatively large area contains numerous intrusive and extrusive units, although a significant proportion of the rocks which crop out are pre-Tertiary ,_Skye_Central_Complex. Metamorphic fluorine reactions in silica deficient dolomite have been investigated between and ° C in the pressure range from to bars.

The equilibrium temperature for the reaction: 1 talc + 7 dolomite + 2 fluorite ⇌ 2 chondrodite + 9 calcite + 5 CO2 + 1 H2O was experimentally determined as a function of the CO2-content of the CO2-H2O gas phase for the total pressure of A Calcic Marginal Facies of the Panticosa Granodiorite, Spanish Pyrenees by R.

() The zoned contact-skarns of the Broadford area, Skye: A study of boron-fluorine metasomatism   The occurrence of high-temperature calcic skarns is relatively rare, with around 30 being reported worldwide. Here, we report on a newly discovered occurrence of a melilite-bearing high-temperature calcic skarn at Camasunary Bay, Isle of Skye.

The contact metamorphism was caused by the intrusion of the Cuillin Hills gabbro and the later intrusion of the Coire Uaigneich ://Skarns can form during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, meteoric, and/or marine origin.

Although most are found adjacent to plutons, they also can occur along faults and major shear zones, in shallow geother-mal systems, on the sea floor, and at lower crustal
