PRELIMINARY REPORT ON THE GEOLOGY OF THE NELSON AND COLLINGWOOD DISTRICTS.
By E. H. DAVIS.
Nelson District.
In making my observations on the mineral belt which lies to the east of the town of Nelson, three main sections were open to me as indicated in my instructions, viz.:—the valleys of the Maitai and Roding Rivers, and the Dun Mountain tramway; those I supplemented by sections run in right lines across the country, so as to connect my main lines of section; these supplementary lines were, from the Maungatapu on the north branch of the Maitai, over the Dun Mountain to the head of the south branch of the same river, thence over the shoulder of the Wooded Peak to the tramway, and so down into the valley of the Roding River; from the top of the Dun Mountain down Windtrap Gully to the Maitai; from the Heads of the Pelorus, by Mount Morrison, to the Roding River; and lastly, from the Lower Maitai, through Long Gully, up Brook-street Valley, past Jenkins's Coalmine and Poor Man's Valley, over Richmond Hill to the old chrome-mine, three miles to the south of Stratford's in Aniseed Valley.
The fundamental rock of the district is the Maitai slate of Hochstetter, which is very much disturbed, and presents a large syndinal curve, having a north-east axis; the south-east flank of the slates rests on a heavy mass of hydromagnesian rocks, which pass gradually into anhydrous olivine; these rocks are probably all products of metamorphism, and not of true eruptive origin, as stated by Hochstetter,* and it is abundantly evident that they owe their present relative elevation to the denudation of the surrounding formations, and
