Floor Fractured Craters

The craters with the interior, or fractured floor, are among the most interesting of the Moon. All right, you might even say that the large craters Copernicus and Tycho, which do not have a fractured interior are very interesting.

True, these two craters are very interesting, but do they have as many different things as fractured interiors?

Let us consider some examples of fractured craters such as Alphonsus, Posidonius, Gassendi and Petavius. First, they are relatively large craters, with a raised interior and concentric related fractures. Second, these and other fractured interior craters often have several types of channels, concentric craters and dark halo craters. Some cracked interior craters are old enough not to have lightning (except the Taruntius), because they already existed when the basalt seas were being produced, an event that ended approximately 3 to 2.5 billion years ago. Approximately all fractured interior craters are located on the shores of the sea and the current model is that magma was born in the fractures of the basins and deposited under the craters, raising its interiors and generating eruptions of lava in its interiors.

In 1976, Pete Schultz was the first scientist to turn his attention to the fractured interior craters and to highlight them as a modified class of impact craters, he even identified 206 of these craters but never published a list of them.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
