The main zeolite collecting site is located approximately 50 meters up Neer Road from its intersection with Highway 30. This is the proper nomenclature for what is most often just called Goble. There are several other specific localities in the Goble area. The rock is composed of Eocene porphyritic olivine basalt. The flows have highly vesicular tops and brecciated and vesicular bases. Common zeolites, thomsonite, mesolite, chabazite, cowlesite, garronite, heulandite are abundant in the upper vesicular area and brecciated/vesicular bases. The rare zeolites, tschernichite and boggsite, and high silica minerals, mordenite, chalcedony, erionite, and okenite are found in the poorly vesicular center of one flow in an area no larger than 2x3x9 meters that is known as the Neer Road pit.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Pleistocene
0.0117 - 2.588 Ma



ID: 2727522
Lacustrine and fluvial sedimentary rocks

Age: Pleistocene (0.0117 - 2.588 Ma)

Stratigraphic Name: Willamette Silt; Gresham Formation; Estacada Formation

Description: Unconsolidated to semiconsolidated lacustrine clay, silt, sand, and gravel; in places includes mudflow and fluvial deposits and discontinuous layers of peat. Includes older alluvium and related deposits of Piper (1942), Willamette Silt (Allison, 1953; Wells and Peck, 1961), alluvial silt, sand, and gravel that form terrace deposits of Wells and others (1983), and Gresham and Estacada Formations of Trimble (1963). Includes deltaic gravel and sand and gravel bars, in pluvial lake basins in southeastern part of map area. In Rome Basin, includes discontinuous layers of poorly consolidated conglomerate characterized by well-rounded, commonly polished pebbles of chert and pebbles and cobbles of quartzite. In places contains mollusks or vertebrate fossils indicating Pleistocene age; mostly deposits of late Pleistocene age, but locally includes some deposits of early Holocene age. Includes Touchet Beds of Flint (1938), deposits of valley terraces of Newcomb (1965), and, in southeast Oregon, basin-filling deposits that incorporate Mazama ash deposits (Qma, Qmp) in the youngest layers
