Summary
| Description |
English: Plate XVIII, Figure 2 of 1898 publication called Maryland Geological Survey Volume Two. Caption: "Edmondson Avenue" Quarry, Baltimore. The text of the book refers to this figure as follows: As shown upon Plate XVIII Fig. 2, the rock of this quarry is a gneiss inclined at an angle of 30 degrees and dipping to the northwestward. The general strike of the beds conforms to that of the area which is north 45 east. As is the case of the Jones Falls quarries, the rock exposed in the quarries varies considerably and furnishes two marked grades of material, one which is almost pure quartz resembling a quartzite and the other a much more feldspathic and micaceous aggregate very similar to the granite but showing a greater or less perfection in its bedding. |
