How this rock got the name is an interesting one. A very few people are aware that this particular rock type is named by famous well-known British India geologist T. H. Holland in 1893 after Job Charnock, purportedly the founder of Calcutta City (now known as Kolkata). Holland, who was with Geological Survey of India. came up with the first scientific study of rocks from the tombstone of Job Charnock in St. John's church in Calcutta. The pink colored granite mined near St. Thomas Mount area of Madras (now Chennai) was specially brought to this place to build the mausoleum for Charnock, a great administrator with East India company. Earlier it was known as Pallavaram gneiss. Pallavaram is also a suburb of Chennai.
