Sisco lamproitic Sill

Sisco lamproitic body (Fig.1) is a small sill that cuts through Alpine high-pressure metamorphic terrain occurs in Corsica, north of Sisco village.

Fig.1: Schematic geoligical map of Corsica showing the location of Sisco lamproite (after Zwart and Dornslepen 1978).

The Sisco lamproite is a leucite- and plagioclase-free ultrapotassic rocks with intersertal texture and a parageneses made of phlogopite, clinopyroxene, olivine (altered), sanidine, and K-richterite associated to subordinate abundance of chromian spinel, ilmenite, pseudobroockite and priderite. Rare roedderite has also been found. The age is about 14 Ma. The Sisco rock is a peralkaline high-silica lamproite exhibiting high concentrations MgO, Ni, Co and Cr and moderate Sc and V abundances.
The Sisco lamproite has a peralkaline index > 1, with high MgO (6.4-7.1 wt.%, Peccerillo et al., 1988). Sisco lamproite has the highest K₂O and the lowest Al₂O₃ among the whole Central Mediterranean lamproites
