The map is accompanied by a marginal explanation consisting of a Description of Map and Database Units (DMU), a Correlation of Map and Database Units (CMU), and a key to point-and line-symbols. (2) Separate .pdf files of the DMU and CMU, individually. (3) A PostScript graphic-file...
2.2.2 Preparation of the Map (1) Determination of criteria: The numbers and codes of the intrusions were denoted by means of ‘lithology + era’ in accordance with Geological Symbols Used for Regional Geological Maps (GB 958−99). At the same time, the lithologic characteristics of the...
You'll learn how to interpret the symbols on a geologic map that represent the surface exposure of sedimentary layers. You'll also get a start on how the information from this surficial data can help estimate what the formations look like underground. ...
5A). The contour map suggests that the crust is relatively thinner in the western QOB during this period and has started to thickening in the eastern QOB (Fig. 6A). Figure 5 Changes of calculated crustal thickness from Sr/Y and (La/Yb)N over time for the South Qinling Belt (A) and ...
1) and where the subsidence map allows for carbonate accumulation. Moreover, it can be noted that carbonates in this area are sufficiently far away from siliciclastic sources. All these factors contribute to the dominant influence of parameter #29 on the result on the sedimentary process. ...
The primary categories are: 1) General Information, which includes fundamental map elements, lithologic key, and explanation of geologic symbols; 2) Presentation and Legibility, which includes appropriate colors/shades, map legibility, and map and key agreement; 3) Primary Geologic Information, which...
