Overlaying various components of interval data is a task most geologists will take when reviewing drilling data. Various interval data will often have different start and ends, different numbers of intervals, or different interval lengths. You can combine them all together using the Interval Compositing tool in Origin.
Below, we see two drillholes with lithology intervals on the left and gold assay intervals on the right. Notice that the lithology intervals are much longer than the assay intervals.
Here is the lithology and assay data for one of those holes in table form:
You can combine these two interval tables into a single file, load it into your drillhole database, and display the result in the Vizex with the Interval Compositing tool. The Exploration license component will give you access to this tool on the Drillhole ribbon:
When you open the tool form, put your input files into the Source File A and B sections.
There are a few ways to combine the intervals. In my case, I want all the data and interval starts/ends to be preserved, so I choose "FROM A AND B".
On the Output tab, enter a file name. I left most options as the default, but included options to add the output file to my drillhole database and load it into the Vizex.
After running the tool, we get this result. I'm displaying the new combined interval file on both sides of the drill trace to illustrate that the intervals are now split to match the original assay intervals, while the lithology values have been preserved.
Here's the table view for the combined interval data and the lithology data. Notice that the combined interval data has gold assay (AU1) and lithology in a single table. Now you can take that combined data and run various statistical analysis to develop a deeper understanding of things like grade distribution in various rock types!
