Page 11 - Probibly three-fourths of the geological facts are recorded cartographically. In consequence, therefore, a modern geological map is a graphic summary of a vast amount of useful information. In addition to an accurate representation of the ordinary geographical features, as in the best atlases, a properly constructed geological map records much more. On it are indicated, within a few feet, the...

The map also forms a reliable soil index which, with some additional explanation serves also as a guide to the distribution of the forests and plants generally. But all the districts of the State cannot be treated alike in the mapping. Some places require far more work than others, either on account of the great importance of the mineral deposits or the natural difficulties caused by the ruggedness...

Page 49 - The true stratigraphic and structural relations of this formation, however, seem not to have been recognized. It appears generally to have been considered of Lower Coal Measure age, and to have been correlated with the inter-stratified sandstones of the Lower Coal Measures, referred to on other pages of this report. The peculiar conditions of occurrence of this formation have, however, received no satisfactory explanation in print, to the writer's knowledge.
Page 13 - Thus, one formation is abundantly supplied with coal, another with the ores of zinc and lead, a third with materials for the manufacture of cements, and others with still different substances of economic value. Each is found in a particular geological zone, and rarely or very sparingly elsewhere. Only within certain districts would search for a given substance be successful; outside of these areas no amount of prospecting would ever disclose the material sought.

Upon it may be based models of the more important districts which are to be taken as characteristic of much larger areas, and which are to represent in a graphic manner the structure, arrangement and relations of deposits. Eventually a relief model of the. entire state may be constructed on a suitable scale. Besides for the purposes mentioned, it would afford one of the most instructive objects for presenting to the pupils of schools the geographical features of their state. With...
Page 14 - At the outset a clear understanding of the geological structure of the rocks containing it is of prime importance. The localities where each occurs require description ; the arrangement, relations and extent of the deposits must be defined; the origin and properties discussed; the accessibility and value determined ; the uses of the substances, the nature and status, both present and probable future, of the industries connected fully considered.

Only within certain districts would search for a given substance be successful; outside of these areas no amount of prospecting would ever disclose the material sought. In obtaining information concerning each particular mineral substance, the entire subject must be carefully considered.

Page 49 - The peculiar conditions of occurrence of this formation have, however, received no satisfactory explanation in print, to the writer's knowledge.! The theory here advanced concerning this deposit is that it is of fluvial or lacustrine origin, that it fills a channel which was eroded in the surrounding, regularly deposited strata, during a temporary emergence of these strata from beneath the waters of the Coal Measure swamp. The leading reasons for this conclusion are briefly the following : 1. The...
