Default Martian volcanoes and meteor impacts

Did large meteor impacts cause volcanoes on the other side Mars?
Here's approximate locations for those regions indicating
a rough correlation as global opposites.

Largest Martian volcanic area
Tharsis-Olympus Mons region 240 E, 10 N
Largest Martian meteor impact
Hellas Impact Basin 70 E, 40 S

Next largest Martian volcanic area
Elysium Mons volcanic region 150 E, 25 N
Next largest Martian meteor impact
Argyre Impact Basin 320 E, 50 S

In sci.space.science stated that:

Largest Martian volcanic area: Tharsis-Olympus Mons region

This is an old idea. Actually it's Hellas and Alba Patera. I think this was
first brought up by Peterson in 1978:

Title: Antipodal Effects of Major Basin-Forming Impacts on Mars
Authors: Peterson, J. E.
Journal: LUNAR AND PLANETARY SCIENCE IX, PP. 885-886. Abstract. TKO.
Publication Date: 00/1978
[ http://adsbit.harvard.edu/cgi-bin/np...;filetype=.pdf ]

More recent publications on the idea are e.g. the following
and the references therein:

List:
[ http://adsabs.harvard.edu/cgi-bin/np...=YES&version=1 ]

Title: Assessment of antipodal-impact terrains on Mars
Authors: Williams, David A.; Greeley, Ronald
Affiliation: AA(Arizona State University, Tempe, AZ),
AB(Arizona State University, Tempe, AZ)
Journal: Icarus (ISSN 0019-1035), vol. 110, no. 2, p. 196-202
Publication Date: 08/1994
[ http://www.sciencedirect.com/science...9376bb7ea0905b ]

Title: Antipodal Hotspots on Earth: Are Major Deep-Ocean Impacts the Cause?
Authors: Hagstrum, J. T.
Journal: Impact Cratering: Bridging the Gap Between Modeling and
Observations, February 7-9, 2003. LPI Contribution No. 1155.
Houston, TX: Lunar and Planetary Institute, 2003., p.27
Publication Date: 02/2003

Do you believe in astrology? Jupiter exerts less gravitational influence
over a human body than does an angry rhino less than two meters away...

Mariner 10 found a similar crater/highland pair on Mercury. 65 million
years ago Yucatan and India weren't far off being antipodal.

Interesting reading. Missed the Icarus impact basin which weakens the
hypothesis. As followups are set to sci.space.science, from where I'm
not posting, and as those followups remove all other newsgroup
references, it usually occurs thread is automatically discontinued
by follow ups, unless as you did, follow up is mentioned in body
of message and I think to manually include newsgroup I'm watching.
