Earth's inner core is older than previously thought
Phys.org
According to recent estimates, the Earth's solid inner core started forming between half a billion and one billion years ago. However, our new measurements of ancient rocks as they cool from magma have indicated that it may actually have started forming more than half a billion years earlier.

Pluto's peculiarities revealed in new photos
Scientific American
It might be just a dwarf planet, but Pluto has at least one thing in common with Earth: both have a blue sky. Earth's blue sky comes from the scattering of sunlight by tiny nitrogen molecules in its atmosphere, but the recipe for Pluto's sky has a few more ingredients. The blue haze there is due to sunlight triggering chemical reactions in nitrogen and methane high in the atmosphere.

Volcanic eruptions influence the flow of major rivers
UPI
A new study, published in the journal Nature Geoscience, offers the first exploration of the relationship between major river flows and volcanic eruptions. Previous research has suggested that major volcanic eruptions can cause a shortage of precipitation in places around the world. Volcanic ash can block sunlight and thwart rain cloud formation. Researchers at the University of Edinburgh looked at how this climatic domino-effect influences rivers.

New England Aquifers: Elusive and Complex Conference — Registration open
AIPG
This is a half-day workshop was developed to provide water utility personnel, engineers, hydrogeologists, regulatory officials and other interested persons in understanding about the sand and gravel and bedrock aquifers their wells are located in and how and why well performance declines over time along with options that are available to rehabilitate your well. The workshop begins with an introduction of the geology and aquifers of New England. From plate tectonics to glacial geology along the effects of weathering that have created the majority of high-yield aquifers located throughout New England. A quick trip through well types, water well terminology, groundwater flow into well screens and a discussion of specific capacity as it applies to sand and gravel and bedrock aquifers. Specific capacity is easy to calculate and use as a measure of the performance of your well, but something that is often overlooked. Moving forward, there is a segment on declining well performance including a discussion of the chemical, physical, and microbiological factors that are the cause for drop in performance in wells. Improving the performance of your well will be discussed by examining physical and chemical methods to rehabilitate your well and improve specific capacity. Understanding the permitting considerations along with the costs of well rehabilitation services will be discussed. The final segment of the workshop will be case studies on well rehabilitation. This will tie together all of the other segments of the workshop.

Earth Science Week: Oct. 12-16
AIPG
The 2016 geosciences contribution to the national GDP is projected to be $73.8 billion. Oil and gas extraction would account for 31 percent of this contribution, with general industry following closely at 29 percent. Although industry relies on trained geoscientists, the decrease in geoscience undergraduate students is projected to lead to a workforce shortage in 2022. Earth Science Week is an opportunity to recognize the societal benefits of Earth science and encourage Earth science education.

INDUSTRY NEWS


Subduction zone formation finally explained
Lab News
Geologists have explained how subduction zones — zones where one tectonic plate moves under another and sinks into the mantle — form. A research team at the University of Nottingham used samples from the Amami Sankaku Basin in the northwest Philippine Sea and found that the crust was much younger than expected. This indicated spontaneous formation of the subduction zone where one tectonic plate sinks because it is denser, rather than the plates being forced together by pressure.

Rocks from ocean floor show earliest evidence of photosynthesis
Tech Times
Geologists from the University of Wisconsin-Madison have found the earliest known evidence of oxygen on Earth, in rocks that were formed on the ocean floor 3.2 billion years ago. Cyanobacteria, which are ocean-dwelling bacteria that create their own food, are likely the first organisms that created oxygen on our planet. That oxygen left a footprint in rocks gathered in South Africa.

Drilling for gold: Inside the KSM's exploration project
Alaska Public Media
British Columbia's Kerr-Sulphurets-Mitchell mining project wrapped up its 2015 exploration season in late September. The KSM, about 30 miles east of the Alaska border, is the largest of 10 or so such projects near waterways that flow into Southeast. Its owner, Toronto-based Seabridge Gold, has already spent close to $200 million searching for ore. We take you there, during the previous season, to learn about the exploration process.

Exploration is multidisciplinary: Exploring the relationships between geologists and biologists
Geology for Investors
Often biologists and geologists are portrayed as being at odds on their views of resource development. Biologists are typically seen as only wanting to stop or slow down natural resource development, while geologists are usually the proponents of such projects. This is unfortunate since geologists and biologist actually have a lot in common, and regularly work closely when it comes to the development of mines.

Exploratory wells in Monterey's deep basin 'unlikely to be successful'
NGI's Shale Daily
In the first means assessment of unconventional, technically recoverable resources in California's Monterey formation in the deepest parts of the San Joaquin Basin, federal geologists have determined it contains an estimated 27 Bcf of natural gas, 21 million bbl of oil and 1 million bbl of natural gas liquids, smaller than previous estimates. The U.S. Geological Survey issued the unconventional resources report on Oct. 6.

Mapping as Mexico opens for exploration
The New York Times
Now that Mexico's potential oil and gas riches are open to outside investment, how does the industry figure out what's there? North of an east-west line across the Gulf of Mexico are United States waters, where the bedrock deep below the ocean floor has proved to hold vast reservoirs of oil and gas. But south of that line, there is very little information.
