In Prospecting For Lode Gold, Gregory Stone presents the background
in geology and mineralogy which will enable the reader to search
out the likely areas for finding lode gold deposits and how to
recognize the clues to their exact locations. He advises on the
most useful tools for prospecting, how to judge the value of the
ore discovered, and, if gold is found, how to proceed with the
claim and protect it. Detailed illustrations and pictures combine
with the text to give a practical and worthwhile background to all
those who find pleasure and, hopefully, profit in searching for
gold.
A. C. Hamlin's two classic books (collected together in one volume)
on the famous tourmalines of Mount Mica, Maine, discuss the history
and illustrate the beauty of these gemstones. A wonderful addition
to any rockhound or mineral collector's bookshelf.
Ancient civilizations used the finest stones to set into their
idols, decorate their temples, and to adorn themselves. These
people used all different sizes and colors of gemstones and these
gemstones were set in sliver, gold and other minerals that they
made metals. Gemstones made legends of both wealth and history in
many parts of the world. Using richly colored gems in trading,
inlaying them in jewelry, jeweled crowns, and garments were just a
few ways that created that gleam and glitter when rays of light hit
a stone. The play of colors giving the gemstones stunning effects.
Leaders, kings, priests, medicine men, and others have put many
different values on rocks and gemstones. A few of these values are
monetary, symbols of great power, healing energies, spiritually and
great wealth. In the world today rocks and gemstones are used as
they were yet in ancient times and for many of these same reasons.
Gemstones both semi-precious and precious are used some way or
another by almost every age group, sex and personality. Each stone
has a different energy and purpose. In some instances a thrill of
excitement is felt by a person just looking at, using or owning a
gemstone. Colorful and cut gemstones attract attention because of
their beauty and ability to move energy levels and states of mind
according to their vibration levels. This statement is also true
for all of the uncut stones in the mineral kingdom.
The locating of a placer gold pay streak is not an easy task, but
in Placer Gold: Where To Find It Gregory V. Stone imparts to the
layman ten years of study and prospecting expertise to make finding
a placer gold pay streak a fine possibility for the reader who
heeds his advise and exerts sincere effort. Written with cookbook
clarity, this guidebook is chock full of detailed illustrations and
geological placer gold clues to enable the reader to search out
likely areas for placer gold deposits.
This title explores how mountains have risen only to dwindle to
dust. Readers discover how igneous, sedimentary, and metamorphic
rocks live, die and are reborn as part of the never-ending rock
cycle.
The book is divided into four sections, minerals, crystals, rocks
and ores. Section A incorporates nine s, begins with presenting
salient features of the earth--its structure and composition. The
second Minerals and Mineralogy briefly tells about their diversity
and their categorisation and introduces the interesting way they
are named. Crystal chemistry the third is the heart and soul of
mineralogy and deals in somewhat details about the building blocks
of minerals -atoms and ions and the way they form diverse types of
minerals are. It tries to tell why every combination of chemical
compounds cannot result into a naturally occurring mineral. The
fourth and fifth s deal with Properties of Minerals, physical and
optical. The s describe various physical properties that are
helpful in the identification both in hand specimens and as thin
section under the microscope. These two s are adequately aided with
a number of illustrations, photographs and photomicrographs to
bring home the point. five deals with classification of minerals
and their occurrence and forms a prelude to the next two s on
descriptive mineralogy. Important silicate and non silicate
minerals are described in s eight and nine. A brief description of
mineral uses is dealt with in both descriptive mineralogy as well
Section D on mineral deposits, however, the last , Mineral uses
presents an overall picture and will be interesting as well as
educating to students and even general readeSection B is devoted to
crystals and crystallography. one introduces the subject while two
presents basic crystallographic elements. three deals with the main
six crystals systems while also giving a preliminary idea about
stereographic projection and x-ray crystallography. Section C
covers petrology, beginning with introduction to science of
petrology, rock nomenclature. two is devoted to the study of
igneous rocks, including their forms, composition, textures,
structures, classification and description. Sedimentary rocks is
the theme of three while different aspects of metamorphic rocks
including kinds and agents of metamorphism and classification and
description of metamorphism. The last portion of this also
considers metamorphism in the background of global tectonics. five,
the rock cycle presents a concise summary of geological events that
have shaped the planet earth. The last section D is what geology is
all about for a man on the street and its significance in nation
building--the Ore minerals. It begins with what ore is and its
place in human affairs as a well as presenting the important
terminology in economic geology. two deals with ore genesis and
presents various hypogene and supergene process that carves out ore
deposits from non economic materials. three, mineral deposits and
global tectonics is becoming a very popular theme among the earth
scientists. A brief introduction of the same will be certainly
appreciated by the student community and prompt them for further
study in this direction. A general survey of India's mineral
resources is the theme of four. It covers almost all of the
commonly used ores, metallic, non metallic or fuels. The last of
section D and the boom, 'Indian mineral industry: some facts and
figures' will present where our country stands in the realm of
mineral resources. Latest available data of resources, production,
export, import, organisations that matter and other useful facts
and figures are presented.
According to the idea of intelligent design, nature's complexity is
the result of deliberate planning by a supernatural creative force.
To date, most scientific arguments against this form of creationism
have been made by evolutionary biologists. In this volume, a team
of earth scientists reveals that the flaws of intelligent design
are not limited to the biological sciences. Indeed, the geological
sciences offer some of the best refutations of intelligent design
arguements. "For the Rock Record "is dedicated to the proposition
that the idea of intelligent design should be of serious concern to
everyone. Editors Jill S. Schneiderman and Warren D. Allmon have
gathered leading figures from the geological community with a wide
range of viewpoints that go to the heart of the debate over what is
and is not science. The purveyors of intelligent design theories
and its kindred philosophies threaten the scientific literacy that
our society needs by confusing faith and the practice of science.

This book is a report on 50+ years of collecting paleopoint data in
Virginia. It contains drawings, rubbings, and photographs of 1055
Paleoindian projectile points. All point data is listed which can
be obtained on a CD from the McCary Fluted Point Survey of
Virginia. The Survey publishes an annual point update which is
available from the Survey. The author can be contacted at:

This 1863 work by an eminent geologist remains among the best
accounts of an important branch of knowledge. The majority of the
text offers an empirical statement of the evidence available in the
mid-19th century regarding human existence during prehistoric
times. The rest of the book considers the connection between
Darwinian theory. 58 figures.
