RICH IN MINERALS
A REPORT IS MADE ON
WESTERN KENTUCKY
Christian, Trigg, Caldwell,
Livingston and Lyon Are
Commented On.

The United states geological survey
has just published All interesting and
valuable report on the lead, zinc and
nuorspar deposits Of Western Ken
lucky. The report is Ia two parts,
aud WAS prepared by Messrs. +. o.
Zurich aud w. 5. Tangier Smith.
The deposits investigated are stu
Ated In Livingston, Crittenden and
caldwell, and adjacent portions Of
lChris,iAn, Trlgg and Lyon counties,
and Ia this counties Immediately
ACROSS the Ohio river In the extreme
southeinportion Of Illinois.
The surface Of the area lie is gener-
ally rolling and more or less irregu-
lArly broken. Some comparatively
level uplands appear, hut they are
always Of rather small extent. The
irregularities are due primarily to
conditions esulting from the abund-
ant iaulting 10 which the region has
been subjected.
This district il usually considered
minor division II the lead and zinc
districts Of the Mississippi valley,
, but ~ In some ways rather sharply
distinguished from the other districts
II the valley. II differs from them
. chiefly In the following respects: Cd
b In the presence Of basic lgneous

% ores, shich are found principally In
true assure veins that have resulted
from irActuring aud subsequent fault

aud zinc are Of primary Importance
= while In this region the igneous dixie
