its differences being due to contact with IIk- granite. All the rocks t)f 
the island have been subjected to intense dynamic action and a num- 
ber of minerals have been developed in the schists, among which arc 
garnet, andalusite and ottrelite. Cutting the rocks of the island are a 
series of dikes whose structure and composition ally them with the

The Geomorphof/eni/ of the Coast of northern California. By Andrew C^. 
Lawson. Bulletin of the Department of Geology, University of Cali- 
fornia, vol. I, No. 8, pp. 241-271. (Berkeley, Nov., 1894.) This paper 
supplements Prof. Lawson's former study of the diastrophism of the 
California coast south of San Francisco (reviewed in the Am. Geolo- 
gist, vol. XIV, pp. B35-338, Nov., 1894). The sequence of the Pliocene, 
and Pleistocene history of the coast farther north is given as follows: 1. 
The development in Pliocene time of a great coastal peneplain, with 
correlative accumulation of marine sediments. A delta formation in 
Humboldt county, called the Wild-cat series, measures about one mile 
in thickness perpendicular to the dip of the strata, which ranges from 
15° to 25°. 2. The orogenic deformation of parts of the peneplain and 
the folding of the Pliocene strata, the general altitude of the peneplain, 
where not so disturbed, remaining about the same. 3. The reduction 
of the upturned soft Pliocene strata to base-level, and the limited exten- 
sion of the peneplain in between the uplifted blocks of the other dis- 
turbed areas. 4. Pleistocene epeirogenic uplifting of the peneplain, 
with its residual monadnocks, to an elevation for the plain of from 1,- 
600 to 2,100 feet above the sea level, the adjacent mountainous tracts 
participating in the same movement. 5. The advance in the new geo- 
morphic cycle to a stage of late adolescence or early maturity. G. A 
very recent local sag or depression of about 100 miles of the coast adja- 
cent to the Golden Gate, and the con.sequent flooding of the stream val- 
leys by the ocean. The subsidence known by the depth of water in the 
narrowest part of the Golden Gate is at least 378 feet. 
In the vicinity of cape Mendocino, which is in Humboldt county, the 
early Pleistocene epeirogenic movement appears to have elevated the 
land for a geologically very short time to an altitude about 3,000 feet 
above its present hight, as shown by the submarine fjords which Prof. 
George Davidson has found by soundings for the U. S. Coast Survey. 
This maximum extent of the uplift is not considered in the present 
paper, but it seems to have been very important in its results as the 
chief cause of the accumulation of the Pleistocene ice-sheet, having 
been a part of the great epeirogenic uplift which affected the whole 
width of the continent to the mouth of tlu' Hudstjii river, with its simi- 
larly deep submerged fjord. w. r.
