Petrographical characteristics of Ditró (Orotva) diorites, Eastern Carpathians, Transylvania (Romania)
One of the most important rock groups outcropping in the NW part of the Ditró syenite massif, north of the Orotva creek and between the Csibi Jakab and Tászok creeks is the group of the dioritic rocks. On the basis of the mineralogical composition, color index (M) and the textural characteristics, t...

| 520 | 3 | |a One of the most important rock groups outcropping in the NW part of the Ditró syenite massif, north of the Orotva creek and between the Csibi Jakab and Tászok creeks is the group of the dioritic rocks. On the basis of the mineralogical composition, color index (M) and the textural characteristics, this rock group can be divided into the following rock types: (1) meladiorites:meladiorites with textural ordering, meladiorites without textural ordering, schistose meladiorites; (2) normal diorites: diorites with textural ordering, diorites without textural ordering, feldspar schlieren diorites,diorites with feldspar aggregates; (3) leucodiorites: leucodiorites with textural ordering, leucodiorites without textural ordering. As the 1:5000 geological map of the area shows, these diorites do not form layer like and lenticular bodies (as some researchers have suggested), but they are irregular rock bodies showing gradual transition and joggle toward the neighboring rocks. Diorites represent a connection between the homblendites and the metamorphic rocks as well as between the syenites, monzonites and granites. To form this tectonic setting two (spatially equivalent but temporally different) magmatic mass had to be intruded. | |
