| Resumo: |
The oldest sediments on Curaçao are jasper¹), diabasetuff, siliceous slates²), radiolarian chert³), quartzporphyrite-crystal tuffs, porphyritecrystal tuffs, lithic porphyrite tuffs, tuffites, tuffite breccias, aphanitic crystal tuffs, tuffite-shales, graywacke-shales and graywackes4). This group of rocks — the Knip-series — is named after the plantation Knip. The stratigraphic sequence of the Knip-series is difficult to ascertain. They are intensively folded¹). I believe it would be safe to assert, that the oldest sediments of this series are jasper and diabase tuffs. The North limb of the anticlinorium in North-West Curaçao is very intensively folded, the South limb, however, in lesser degree, so that on the plantations Sint Jan, Groot St. Martha, St. Nicolaas, Spaansche Put, St. Kruis and Lagoen (Seroe Commandant), more can be seen of the sequence of the strata. Even so this is not much, as a large part of the Knip-series has been carried away by later denudation.
