在整个西北非洲,出现了许多小型的、浅成侵入的晚古生代复合深成岩体,摩洛哥的蒂奇卡岩体是这些深成岩体中出露最好的一个,最近Vogel和Walker(1975)、Termier等(1977)已对它做过描述。 最重要的野外关系是普遍出现扁透镜状的花岗岩体被成分为辉长岩到闪长石的复杂组合所环绕的常见的产状。岩体野外关系曾被解释为酸性和基性岩浆在 Throughout Northwest Africa many small, shallow-Paleozoic complex deep plutons have emerged, with the Dioccanic rock in Morocco being the best exposed of these plutons. Recently Vogel and Walker (1975), Termier et al. (1977) has described it. The most important field relationship is the widespread appearance of flat lens-like granites surrounded by a complex assemblage of gabbros and diorite. Rock mass field relationships have been interpreted as acidic and mafic magma
