TRIBUNTRAVEL.COM – An article published in GSA Bulletin 2017 reveals surprising information about the uterus old lake it's about March. In the report, it was stated that old lake sure March resembles lake sediments in Towuti, South Sulawesi.
Timothy A. Goudge, an expert from the University of Texas, said that Towuti Lake is ofiolite, consisting of rocks rich in iron and magnesium (mafic). This is more similar to the surface Mars that most land land on Earth, usually more felsic or more rich in silicon, aluminum, sodium, etc.
Goudge and the team detailed the clay mineralogy of Towuti Lake, Indonesia, to find out.
This complementary study also uses a technique called Near Infrared Spectroscopy (VNIR).
The spectral results of Lake Towuti show different variations of clay minerals over the past 40,000 years.
The technique also records the response of the lake system to climate change, including lake level changes, artificial delta progression, and river slices.
According to Goudge, this shows that VNIR spectroscopy can be used to develop environmental recordings for tens of thousands of years.
The interest of this research is Goudge and the team also discovered that the deposit old lake sure March the possibility of storing paleoenvironmental information similar to that accessible via remote sensing stratigraphy and VNIR spectroscopy.
Goudge added that the makeup relationship between Lake Towuti and Lake Mars is not perfect. Therefore, Goudge puts more emphasis on the use of VNIR techniques.
Goudge added that they could distinguish various materials with colors, such as rust with red because they contained iron. Thus, VNIR spectroscopy allows humans to determine the minerals present in lake sediment samples.
The technique is indeed relatively new to be practiced against lake deposits on Earth. Nevertheless, this technique can operate at a great distance using only reflected light from the sun. Therefore, the technique can be used to study mineralogy and surface composition on other planetary bodies, including March.
"Our research shows that it is possible to use VNIR spectroscopy to understand the climatic evolution recorded in the past by lake sediments. That's why we propose to apply the same approach to the study of deposits. old lake sure March with a high resolution, which will help reveal the climate history March old-fashioned, "said Goudge.
