NOTES ON A BASALT-VITROPHYR AT TANJIL. 
By A. W. Howann,.'l).G-.S. 
Cd 
I am indebted to the courtesy of Mr. Graham, the mining manager 
of the “Tanjil Deep Leads Goid Mining Company 3 for the 
samples described in these notes. According to the information 
which he favoured me with, the No. 2 shaft of the mine was sunk 
through a vyoleanic flow, which had covered and preserved from 
erosion part of the course of a former river, of which perhaps the 
Tanjil is the modern representative.* 
In sinking the shaft, a tree trunk was found standing erect and 
enclosed in the rock from which the samples Nos. 1 and 2 were 
taken. Mr. Graham states that “it rested in a ollow in the clay, 
but without any sign of tap root, and the remaining branches and 
roots had a charred appearance.” At 82 feet depth, cemented 
gravel was found, which is locally known as “ cement” or “ pudding 
stone,” this was two feet thick, and it rested upon a few inches of 
water-worn gravel. Below this was the bed rock, probably of Upper 
Silurian age. 
The sample of the rock through which the shaft was sunk, is a 
mixture of volcanic glass and fragments of crystalline rock. The 
glassy material which was very abundant in some samples, I found 
to be throughout greatly altered and decomposed, so that I had 
much difficulty in extracting sufficient material in an unaltered 
condition for analysis and examination. he alteration products 
are mostly carbonates of iron, manganese, lime and magnesia, which 
*I may refer the reader to particulars as to the Tanjil district given by 
Mr. Reginald A. F. Murray, in his valuable memoir on the “* geology and 
mineral resources of South Western Gippsland.” Progress Report of the 
Geolegical Survey of Victoria, part III, page 135.
