This occurrence of zeolites is located in a road cut on U.S. Highway 99E about 100 m north of the McKenzie River Bridge. The zeolites occur in a basalt porphyry which intrudes the Eugene Formation. The basalt has large phenocrysts of plagioclase and contains about 70 percent bytownite, 20 percent clinopyroxene, 5 percent nontronite, and 2 percent magnetite. Thomsonite was observed to replace some of the plagioclase near the edges of fractures The zeolites occur within the pluton in a faulted and brecciated zone about 8 m wide. They compose about 2 percent of this zone. The zeolites and associated minerals in order of abundance are analcime, nontronite, thomsonite, calcite. Natrolite, stilbite, laumontite, and pyrite are uncommon.
