find_units
ActiveTool of Macrostrat
Find geologic rock units from Macrostrat by location + age, by stratigraphic name, or by lithology. Provide lat+lng (optionally with age in millions of years, Ma), or a strat_name (e.g. "Hell Creek"), or a lith (e.g. "granite"). Returns units with formation/group, stratigraphic column, bottom/top ages (Ma) and time intervals, lithology, and max thickness. Keyless. North America and beyond.
