New Paper on Putative Saginaw Impact Structure, Michigan 22DEC2018

 New Paper on Putative Saginaw Impact Structure, Michigan

There is a new paper in the Journal of Great Lakes Research
that people interested in impact structures and craters might
miss because it outside the usual reading list of journals.

It is:

J. Klokočník, J. Kostelecký and A. Bezděk, The putative
Saginaw impact structure, Michigan, Lake Huron, in
the light of gravity aspects derived from recent EIGEN
6C4 gravity field model. Journal of Great Lakes Research,
https://doi.org/10.1016/j.jglr.2018.11.013
https://www.sciencedirect.com/science/article/pii/S0380133018302260

I do not know enough about exotic ways of processing
gravity data that are needed to understand "combed
strike angles" represent, to offer any opinion about
they are and represent.

Any comments from experts in interpreting gravity data
are welcomed.

Is Ownership Governed by Surface Rights or Mineral Rights ? 21NOV2018

 Is Ownership Governed by Surface Rights or Mineral Rights ?

This is an interesting legal battle about whether

surface rights or mineral rights determines fossil

ownership.

Fight over dinosaur fossils comes down to what’s a mineral

 By Amy Beth Hanson, AP, Washington Post, November 16, 2018

https://www.washingtonpost.com/business/fight-over-dinosaur-fossils-comes-down-to-whats-a-mineral/2018/11/16/6025a23a-e9e7-11e8-8449-1ff263609a31_story.html

The article states:

"Ownership of two fossilized dinosaur skeletons found on a

Montana ranch in 2006 are the subject of a legal battle over

whether they are part of a property’s surface rights or mineral

rights. The 9th U.S. Circuit Court of Appeals issued  a split

decision saying fossils are minerals under mineral rights laws."

In case of meteorites, would a fall found on the surface be

governed by surface rights and a buried meteorite dug

from the ground be governed by mineral rights?  :-)  :-)

The article stated:

"Next month Sotheby's in New York will auction off some of the only

moon rocks that can be legally owned by private individuals."

As we all know, this is not correct. Lunar meteorites, which are

also pieces of the Moon are legal to buy and sell freely.

They are still pricey. :-(

Galileo's "Sidereus Nuncius Martayan and Lan" 10SEP2018

Galileo's "Sidereus Nuncius Martayan and Lan"

The story of the, at first, successful forgery of
Galileo's "Sidereus Nuncius Martayan and Lan" is quite
interesting. Below, there are an interesting lecture
about, which is initially overly academic, and an
open access book to read about the forgery. It is
interesting how the expectation of a "great discovery"
might have led expert to overlook some "red flags"
about its authenticity.

Some articles are:
