Geologists believed prior to the mission that both of these formations were volcanic in origin ; however, samples returned from the lunar surface have since proven this hypothesis is incorrect.

Geologists use the term " marble " to refer to metamorphosed limestone ; however stonemasons use the term more broadly to encompass unmetamorphosed limestone.

Geologists were hired to research the structure as well as city planners were hired for designing however there were no investors at the time and therefore the project was subsequently abandoned.

Geologists have estimated that a much larger deposit exists deeper and possibly off shore from the peninsula in the 400-500 billion barrel range, however exploration drilling has not yet confirmed this theory.

Geologists also obtain data through stratigraphy, boreholes, core samples, and ice cores.

Geologists and engineers drill core samples and conduct surface surveys searching for specific compounds and ores.

Geologists also study unlithified material, which typically comes from more recent deposits.

Geologists were also concerned that the St. Helens eruption was a sign that long-dormant Cascade volcanoes might become active once more, as in the period from 1800 to 1857 when a total of eight erupted.

Geologists believe that 15, 000 to 25, 000 years ago the Laurentide ice sheet pushed down from Canada across what are now the Great Lakes, and over much of the northern U. S. One of the ice sheet's lobes bulldozed down over two thirds of Taylor county, at its farthest extent covering a line from Westboro through Perkinstown to Lublin.

Geologists have noted the chemical and geological content of these three mountains to be much different than that of the Cascade Range, simply because they are not volcanic in origin, while the entire Cascade Range is postulated to have formed from volcanic action.

The first such laminations were found in a rock called “ The Dells .” Geologists would say that the cross-stratification showed festoon geometry from transport in subaqueous ripples.

Geologists estimate that 18 inches of salt crust have been removed from the flats, and that the reduction of salt happens at a pace of one percent per year.

Geologists have determined that debris from several distinct landslides in the same area overlap, forming what is called the Cascades landslide complex.

Geologists have theorized that this is a rare case of a large natural syphon from a nearby mountain.

Geologists, energy researchers and many other scientists from the following countries are represented in ASPO: Australia, Austria, Denmark, China, Finland, France, Germany, Ireland, Italy, Netherlands, Norway, Portugal, South Africa, Spain, Sweden, Switzerland and the United Kingdom.

The Nimrod Glacier is a major glacier about 135 km ( 85 mi ) long, flowing from the polar plateau in a northerly direction through the Transantarctic Mountains between the Geologists and Miller Ranges, then northeasterly between the Churchill Mountains and Queen Elizabeth Range, and finally spilling into Shackleton Inlet and the Ross Ice Shelf between Capes Wilson and Lyttelton.

The Society of Economic Geologists ( SEG ) originated from a 1919 gathering of a group of Geological Society of America ( GSA ) members who were especially interested in economic geology.

Geologists believe that it is a filled-in kettle formed from a receding glacier.

In November 1926 Wegener presented his continental drift theory at a symposium of the American Association of Petroleum Geologists in New York City, again earning rejection from everyone but the chairman.

or 5000-3000 BC Geologists believe that tectonic activity created elevation changes which redirected the flow of Sutlej from the southeast to the southwest.

Geologists chose the area because of a wide crater created approximately 1. 6 million years ago by a large meteorite.

Geologists who hoped to study what happens before a quake, and in particular any signs that might enable them to predict future earthquakes, installed an elaborate array of seismometers, creepmeters, strainmeters, and other instruments in and around Parkfield starting in 1985.

Geologists are concerned that the Usoi Dam may become unstable during future large-magnitude earthquakes, which are relatively common in the seismically active Pamirs, and might collapse due to liquefaction or subsequent landslides during such an event.

Geologists have proposed several theories about their origin.

Geologists estimate that the Gulf of Guinea zone ( Niger Delta province ) holds more than 10 billion barrels ( 1. 6 km³ ) of oil, although no reserves have yet been proved.

Geologists like Suess have found fossils of ocean creatures in rocks in the Himalayas, indicating that those rocks were once underwater, before the Indian continental shelf began pushing upward as it smashed into Cimmeria.

Geologists have found evidence that a major outbreak of Lake Agassiz, about 13, 000 years ago, drained north through the Mackenzie River into the Arctic Ocean.

Geologists have called this section of the glacier " the Delavan lobe ".

Geologists and geographers have been interested in the area since the beginning of the 19th century, and in the 1830s the first serious study of the area took place.

Geologists have identified at least five separate events which have led to sediment deposition, including the Grenville orogeny ( the collision of continents that created the supercontinent Rodinia ) and the Appalachian orogeny during the formation of Pangaea.

Geologists have found various poorly preserved and badly eroded and rolled marine fossils within it.

Geologists believe they have found evidence of this major earthquake in sites throughout Israel and Jordan.

Geologists have tried to use hotspot volcanic chains to track the movement of the Earth's tectonic plates.

Geologists have recognized innumerable fossil soils ( paleosols ) throughout the strata containing upright fossils at Joggins, Nova Scotia, Yellowstone petrified forests, coal mines of the Black Warrior Basin of Alabama, and many other locations.

Geologists who have studied upright fossils found in sedimentary rocks exposed in various outcrops for the last 30 years have described the upright fossil trees as being deeply rooted in place and typically rooted in recognizable paleosols.

Geologists, such as Falcon and Rygel et al., have published detailed field sketches and pictures of upright tree fossils with intact root systems, which are rooted within recognizable paleosols.

Geologists have also found that some of the larger upright fossil trees found within Carboniferous coal-bearing strata show evidence of regeneration after being partially buried by sediments.

Geologists do not know what happened to the eroded sediment that must have overlain the complex, but they do know that regional uplift was responsible ; the area was originally below the surface of a shallow sea.

Geologists have various theories of what causes shatter cones to form, including compression by the wave as it passes through the rock or tension as the rocks rebound after the pressure subsides.
