Two holes drilled through reef sediments into basalt have established a geologic section through the Miocene. Midway was built above the sea by flows that were weathered and partially truncated in pre-Miocene time. After submergence, volcanic clays were reworked and covered by limestones. Overall ubmergence was interrupted at least twice by emergence. The limestones have been leached, recrystallized, and partially dolomitized. 
Volcanic Island Chains and Sea Floor Spreading
Migration of the centre of volcanism in the Hawaiian Island chain toward the East Pacific Rise with time is accounted for by a model which suggests that counterflow of material in the asthenosphere
Relation of Macdonald Volcano to migration of volcanism along the Austral Chain
The growth of island chains by the linear migration of volcanic activity is manifest, to varying degrees, in the surface geology of a number of island groups. In Hawaii, the classic example, this
Marine Geology of Kure and Midway Atolls, Hawaii: A Preliminary Report
Midway and Kure islands are the world's northernmost atolls but have flourishing algal-coral reefs with typical coral reef structures. An almost circular outer reef and a broad, shallow « 5 meters
Quaternary atoll development: New insights from the two‐dimensional stratigraphic forward modelling of Mururoa Island (Central Pacific Ocean)
Knowledge about the Quaternary evolution of mid‐ocean atolls comes mainly from drilling and field observations carried out on a number of Pacific carbonate islands. However, little is known about the
Relationship of Chautauqua Seamount to Seafloor Spreading in the North Pacific Ocean
CHAUTAUQUA SEAMOUNT is one of a north–south trending group of seamounts 155 km west of the island of Kauai (Fig. 1). We1 described the magnetic and gravity fields of Chautauqua Seamount, and its age
Island subsidence, hot spots, and lithospheric thinning
Drilling results from several western Pacific atolls indicate the long-term subsidence of these islands is much more than would be expected from the cooling and thickening of the underlying


Dolomitization: Observations on the Island of Bonaire, Netherlands Antittes
A mass balance indicates that brine is being refluxed downward today, and the Pleistocene dolomite on north Bonaire could have been produced by similar reflux of brine.
Dolomitization of the Mid-Pacific Atolls
Measurements of oxygen isotopes in samples of dolomite can be interpreted as indicating an origin from evaporated, isotopically-heavy sea water.
Thickness of Coral at Midway Atoll
ON May 25 and 26, 1963, with the aid of staff members of the Scripps Institution of Oceanography and the University of Hawaii, I made a very brief refraction survey at Midway Atoll in the Hawaiian
Structural and Compositional Variations in Some Natural Dolomites
Dolomite concentrates from sedimentary rocks ranging in age from Eocene to Ordovician have been examined by powder and single-crystal X-ray methods. They not infrequently contain about 5 mol per cent

The oriented cores were taken, under the direction of Charles E. Ward of Christensen Diamond Products Company
    X-ray diffraction analysis was used to identify and to estimate the abundance of the carbonate minerals in finely grotund samples
