The garnets from Site 1137 sample a high-temperature/low-pressure pelitic source. Their compositions are in the low-calcium pyralspite field and range from 77 to 57 wt% almandine (17-38 wt% pyrope), the latter high-Mg contents and lack of evidence for zoning suggesting relatively high temperatures. These compositions are entirely consistent with a continental source area of pelitic and granitic materials.
