Description:
Analysis logs are used to present the composition of lithology or balance between
different components displaying each element according to its quantity (in percent)
as graphical pattern. The Data is stored in a two dimensional array, where the first
dimension consist of depth, sampled at a constant rate, and the second dimension
holds the series of percentage values belonging to the different elements. The user
can define the number and type of elements to be handled.
Graphical patterns are user definable and their storage is organized by the means of
lithology dictionaries. Lithology dictionaries can be created, edited and maintained
using LithCAD.
Data Format:
E.g.
Depth, Data1, Data2, Data3, … , DataN
Note that the numbers express a percentage of a certain component. The column
titles are the codes referring to a particular display pattern in the attached pattern
library.
Display Styles:
The Analysis Log supports three different data display styles.
Fixed Bar style: A bar of fixed height is drawn for each depth point.
Dynamic Bar style: A bar is drawn is drawn from one to the next depth point.
