Yes, the information is available. Get the Tide Tables from the U.S.
Hydrographic Office. These are sold by any large marine chart supplier.

Hi, Hayward:
Megnetite is FeO4 (iron oxide). There may be small traces of manganese,
nickel, chromium, and titanium, but its importance is as iron ore when
found in a very large, high grade deposit. The color is iron-black,
metallic, and the streak is black. The hardness is 5 1/2 to 6 1/2. The
specific gravity is 4.9 to 5.2, the fracture is subconchoidal and
uneven. It is brittle, and strongly magnetic.
It is a very common component of many igneous rocks, as well as some
clastic sedimentary rocks. It also commonly occurs with contact
metamorphic rocks, as well as in massive and vein hydrothermal
replacement deposits.
Black sand usually contains a fairly high percentage of magnetite
particles, along with other heavy mineral particles. Very large
magnetite crystals have been found at many U.S. and other locations.

Dear all,
on my www page (under construction) you can find at :
http://psmac5.ess.sci.osaka-u.ac.jp/Journal.html
a list of 200 Earth Science Journals that have a WWW or Gopher page with
Table of Contents, Instruction for Authors etc.
I woul like to enlarge the selection, which will be soon transferred on a
NEXT workstation (actually the page is on a Performa). Anybody has the
coordinates of WWW pages of earth sciences journals which are not listed
in my WWW page can send me a message at
pinti@ess.sci.osaka-u.ac.jp
Thanks to all,
Daniele

Subject: MAN AS OLD AS COAL (some info on raging controversey)
From: edconrad@prolog.net (Ed Conrad)
Date: 17 Nov 1996 10:12:23 GMT
Out of courtesy to those unaware of the ``MAN AS OLD AS COAL"
controversy which has been raging on talk.origins and elsewhere
since last March, a bit of information follows:
The dynamite was ignited on the Internet by Ted Holden when,
as part of HIS home page, he posted:
> http://access.digex.com/~medved/conrad/conmain.htm
which is entitled:
> PETRIFIED HUMAN/HOMINID
> AND OTHER LARGE ANIMAL
> BONE IN CARBONIFEROUS STRATA
It permitted me to have my say in the matter at:
> http://www.access.digex.net/~medved/conrad/contest1.htm
which is entitled:
> MAN AS OLD AS COAL
Just recently, Ted posted two color photos I had sent him, of what I
claim is a petrified human skull embedded in -- and protruding from --
a boulder which had been extracted from between anthracite veins
near Shenandoah, Pa., during a surface-mining operation.
The boulder is mentioned deep into Ted's home page and can be called
up for viewing by turning to:
> http://www.access.digex.net/~medved/conrad/skulla.jpg
A second photo offers a comparison with the contour of a human
skull and can be seen at:
> http://www.access.digex.net/~medved/conrad/skullb.jpg
Naturally, there are vociferous critics. They include Andrew MacRae
of the University of Calgary and Paul Myers of Temple University who
have home pages of their own concerning some of this subject matter.
Their material can easily be found by using Netscape.
The bottom line in the controversy so far -- at least I think so -- is
the insistence by MacRae and Myers that their microscopic evaluation
of the cell structure of a few of my specimens they had examined does
not reveal the presence of Haversian systems.
I have kept telling them that they can look 'til they're blue in the
face because they'll never see the structures surrounding the
Haversian canals as is clearly evident in non-petrified bone.
They don't seem to get the message that, quite simply, the process
of petrification has caused the surrounding structure to disappear,
leaving only the Haversian canals as the proof that the rock-like
objects are bone.
A comparison of photos of the cell structure of non-petrified bone and
the cell structure of one of my specimens can be seen at:
> http://www.access.digex.net/~medved/conrad/c2.jpg
Additionally, a comparison of the interior surface features of
non-petrified bone and one of my specimens -- taken with a scanning
electron microscope (SEM) -- can be viewed at:
> http://www.access.digex.net/~medved/conrad/bones.jpg
If man indeed existed during the coal formations and if science is
correct about one of its golden rules -- that coal was formed during
the Carboniferous, a minimum of 280 million yeas ago -- then the
theory of man's evolution from the lowliest primates of 65 million
years ago has to be thrown out the window.
