Summary:
Santa Lucia quartz diorite. The term Santa Lucia was first applied by Lawson (1893) to the porphyritic granite in vicinity of Carmel Bay, but the porphyritic variety that he describes is only of local extent in Point Sur quadrangle. As it apparently grades into the main quartz diorite mass of the region, and hence is probably a differentiate of the quartz diorite, the name Santa Lucia is retained for the entire plutonic mass. Intrudes Sur series.

Summary:
Evidence is that Santa Lucia quartz diorite has intruded and is later than Santa Lucia granite of Gavilan [Gabilan] Range, and presumably both intrusives cut Sur series.

Summary:
Term Santa Lucia is applied to granitic rocks of Gavilan [Gabilan] Range, since they are considered to be generally related to the granites of Santa Lucia Range. Age is pre-Franciscan.

Summary:
Pg. 118. Several names have been given to the ancient crystalline complex in San Francisco Bay Counties. Originally it was called Santa Lucia series, a name applied to the crystalline complex as a whole. Later, name Sur schists was given to the metamorphosed sedimentary and volcanic rocks, and name Santa Lucia was retained for the plutonic rocks. It has become customary to call all schist the Sur series, all crystalline limestones, marbles, and dolomites, Gabilan limestone, and all plutonic rocks the Santa Lucia granodiorite. These names are essentially petrographic and not formational in usual sense since rocks of very different ages might be included under any one of the names.
