Notes and Questions
Please sign in to write a note for this page
Note: lowercase "f" often resembles "t". Can be distinguished from vertical line as it may be noticeably longer or extends below the line. Easier for words like "for" but can be more difficult for longer, more scientific words like "crustification" like in line C 230, especially if you are unfamiliar with the geological terminology like me.
Note: I have limited experience with geological terminology. This shows in my many single square brackets featuring my best guesses. Google can only do so much. I especially had difficulty with some abbreviations as can be seen in the compositions/descriptions of C226 or C235.
