New science to help oil industry

The study of plate tectonics, or the drifting of plates, will play an important role in the search for natural resources in the earth's crust, Marion Bickford, professor of geology at the University of Kansas, said recently.
Bickford said that as resources became harder to find, the data being collected from basic research in plate tectonics would be supplemented by mineral industries to locate new resources.
The theory of plate tectonics states that the earth's crust is made up of continents and plates. It deals with the drifting and rifting of the continents and plates and their formation, movement, interaction and destruction.
As these processes occur, Bickford said.
some of the earth's natural resources are formed. Thus, through the study of plate tectonics, geologists can locate the formation of new resources.
"THEE IS A DEFINITE relationship between the discovery and discernances of certain metals." Biblard art. 207.
Copper, lead, zinc and iron deposits have occurred at plate boundaries where the metal is buried.
The petroleum industry also uses data from plate tectonics research to find
There is a great potential for new resource discoveries, Bickford said, because platectic data has been used in research for natural resources for only 10 years.
It has been only 15 years since plate
The phenomena, such as the continuity of mountain systems along coastlines, the rock types between continents, the shapes of mountains, and the "almost identical" Permian (280 million years ago) amphibians in both South America and South Africa now are extinct.
tectonics emerged as a theory that explains certain phenomena of the earth, he said.
THE CURRENT spreading of the sea floor is another geologic phenomenon that offers evidence for the theory of continental drifting and rifting.
"The current thinking is, with what we observe now, that the sea floor spreads and new crust is generated at these spreading centers." Bickford said.
As these plates continue to move apart, continents may collide to form new land
masses and perhaps eventually a single land mass, he says. But that will not occur
As an example of that phenomenon, he cited the formation of the Himalayan Mountains.
FOR THE PAST 10 YEARS, Bickford has been investigating the growth and evolution of new species.
"India and Asia collided about 30 million years ago," he said, "and all the sediment that was deposited in the ocean basin that is now the Himalayas mountains."
The research on the continental crust has taken place in the St. Francis Mountains in southeast Missouri, where there is a large exposure of volcanic rocks and some intrusive, or new, rock bodies that have formed beneath them, Bickford said.
Potholes create more car repairs

Although many of Lawrence's pot holes now have been filled, motorists are just beginning to feel the final results of the reforms they have taken during recent months.
The damage to cars from hitting potholes may be greater this year than ever before, according to local auto repair shops. That damage can be anything from a broken steering control arm to a damaged muffler to wheels knocked out of alignment.
The most common problem cause by hitting ooholes is shearing misalignment.
Ben Miller, mechanic for Jim Clark Motors, 2121 W. 29th St. Terrace, said recently he was a "check of a lot of alignment alignments than ever" in his shop.
Al Eaum, Ace Steering and Brake. 10 Minnesota St., said the shop had been really busy in recent weeks.
he noted that it was difficult for the average driver to tell whether he had a minor injury.
UNLESS A DRIVER noticed uneven tire
trend wear, Easum said, one might not
be able to tell.
Cars with power steering tend to mask the problem and still drive properly even when they are off.
The average cost of alignment is $15 in Lawrence.
Tires also take a beating from the potheses this year. According to Joe Bigenwalt, Gregt Tire Company, 814 W. 23rd St., a pothole tends to cut and tear a tire's inside wall and sometimes even dent the metal wheel. A tire with a bolt in the wheel could run anywhere from $80 to $150.
Potholes also took their toll on mufflers. Ken Cowan of Downtown Woolf, 900 Kentucky ST, said that the bad weather and lack of anything that was rusted out to come off.
A POTHLE ALSO "lowers the clearance of the car and the muffler sometimes catches," he said, noting that the shop had repaired more cars than usual this year.
According to Forrest Bookout, co-owner of the T.R.I.E. C20, 729 Ninth St., the company was heavily booked with jobs to repair mutilated damages by the winter and
Bookout said it costs the average car owner from $20 to $30 to replace a muffler and from $13 to $18 more to replace a tailpipe.
Local mechanics also agreed that potholes could cause more severe damage to cars, especially older ones, which tend to be more susceptible to damage like broken
Dave Wilson, service manager at Hillcrest Wrecker, 112 E. 23rd S., said he
towed one car that had a broken steering arm after it haphole.
HAROLD TWIGG, owner of Harold's 6403, Service 1540, W. Sixth St., said the A-frame would break only in extreme cases but also noted that a car could pop out a ball joint if it hut a hole hard enough and that the result could bring it to "a screeching halt."
Estimates to fix a ball joint ranged from $30 to $100 depending on the type of car and estimates to repair the steering arm ranged from $75 to $100.
Overall, though, local repair shops noted an increase in business which they attained by using the Tarpa service adviser for Landmark Ford, 238d and Alabama streets, and business had been able to afford the repairs.
"I even broke a tire myself," Tarpy said.

Sabbatical leave proposal goes to University Senate
By CAROLINE TROWBRIDGE
Staff Writer
A new sabbatical leaves proposal was approved yesterday by the Faculty Council, despite reservations about the budget. Mr. Del Shankel, executive vice chancellor,
The proposal is now subject to approval by the University Senate at its May 4 meeting.
Sabbaticals are one or two semester leaves of absence from teaching and administrative duties at half pay.
The sabbaticals are designed so that advanced study, research, professional or industrial experiences may be pursued.
"I thought there were some portions of the proposal we might have difficulty with." Shankel said.
Shankel said yesterday that if the proposal passed the University Senate, it would be subject to approval by University officials, including Chancellor Alberto R. Dykes, University and the vice chancellor for academic affairs.
MIKE DAVIS, University counsel, said that he and Shankham met with members of the Faculty Executive Committee last week to discuss some reservations about the proposal.
One reservation was that more sab>
batical proposals may be deemed meritorious by the University Committee on Subbatical Leaves members there are positions available, Davis said.
Under the current system, the number of meritorious votes must not exceed the number of sabbaticals available.
The current system also states that eligible sabbatical proposals are to be determined by the record of academic awards of the candidate as well as her merit.
The new proposal bases the choice strictly on the merit of the candidate's proposal.
Proposals that receive seven or more votes from committee members under the new proposal would be deemed strictly meritorious.
TO DETERMINE THE MERIT of a proposal, the new policy dictates that the committee should use the following criteria: the applicant's contributions to teaching, research and services, the value of the sabbatical proposal to the university's professional needs and goals and its value to the department and the University.
If more applications are approved than there are positions available, under the new proposal, preference would be given to applicants who never had a sabbatical.
