Mafic dike swarms are a common expression of mantle-derived magma generation associated with extensional tectonic regimes in post-collisional or intraplate extensional settings (e.g. Rock, 1991).They can thus provide important information for understanding not only the mantle source of the magmas, but also the tectonic evolution …

The Dolerite The dolerite intrusions are mainly in the form of dykes (see Fig. I). In a few places the dolerite has spread laterally to form small sheet-like intrusions. Two of these dykes, representative of two different sets of dykes, were studied fully. Dyke is about 100 ft. wide. It forms a prominent outcrop and is much
