Contains a fine grained, dark grey ground mass. Clasts range from small to large in size and sub-angular to sub-rounded in shape. Minor amounts of lineations can be seen. Certain clasts appear weathered.

Monte Carlo study of the XY-model on quasi-periodic lattices

Monte Carlo Simulations were carried out using a nearest neighbour ferromagnetic XYmodel, on both 2-D and 3-D quasi-periodic lattices. In the case of 2-D, both the unfrustrated and frustrated XV-model were studied. For the unfrustrated 2-D XV-model, we have examined the magnetization, specific heat, linear susceptibility, helicity modulus and the derivative of the helicity modulus with respect to inverse temperature. The behaviour of all these quatities point to a Kosterlitz-Thouless transition occuring in temperature range Te == (1.0 -1.05) JlkB and with critical exponents that are consistent with previous results (obtained for crystalline lattices) . However, in the frustrated case, analysis of the spin glass susceptibility and EdwardsAnderson order parameter, in addition to the magnetization, specific heat and linear susceptibility, support a spin glass transition. In the case where the 'thin' rhombus is fully frustrated, a freezing transition occurs at Tf == 0.137 JlkB , which contradicts previous work suggesting the critical dimension of spin glasses to be de > 2 . In the 3-D systems, examination of the magnetization, specific heat and linear susceptibility reveal a conventional second order phase transition. Through a cumulant analysis and finite size scaling, a critical temperature of Te == (2.292 ± 0.003) JI kB and critical exponents of 0:' == 0.03 ± 0.03, f3 == 0.30 ± 0.01 and I == 1.31 ± 0.02 have been obtained.

Arthur A. Schmon Memorial Trophy

This trophy was awarded to the winners of the 'Great Debate' on whether or not university tuition should be free that took place on October 27, 1965 at Brock's Glenridge Campus Auditorium. The affirmative team comprising of Lawrence Winters, Sean Finley, and Gordon Williams were presented with the Arthur A. Schmon Memorial Trophy after successfully arguing that tuition should be free. The trophy was presented by Board of Governor's secretary-treasurer Edward Mitchelson.

Guernsey Milk Can

In 1969, Sir William Arnold, Bailiff of Guernsey - the birthplace of Sir Isaac Brock - was invited by Dr. Gibson to come to Canada and visit Brock University on the 200th anniversary of Sir Isaac Brock's birth. Following his visit in October of that year, the Bailiff presented Brock University with this miniature silver milk can. This milk can is of the traditional Guernsey style.

Vice Chancellor Trophy

Trophy awarded for extra curicular and academic excellence. The trophy was first awarded to Ian Beddis by Dr. Gibson in 1967.

Alumni Association Award

Brock University Alumni Association Award for Excellence in Teaching.

Gavel

An ornamental wooden gavel with brass plate from the 1965-66 Brock University Student Assembly. The inscription on the gavel reads: Don Chapman, Brock University Student Assembly, Speaker of the House, 65-66.

Brock Frosh Beanie

This Brock Frosh Beanie from around 1965 is made of red and blue felt with white stitching. An identification button with 'Barb' inscribed on it with black marker is attached to the left side. The Frosh Beanie and identification button were available for students to purchase immediately after registration.

Brock Scarf

This Brock scarf is made of a navy and scarlet wool blend.

Gibson Tie

The Brock University tie was cut from a bolt of silk manufactured in Sussex, England. This was the first of 100 Brock ties specially ordered from Swords Custom Furnishings of Toronto. Dr. Gibson received this tie in May of 1967. The tie was eventually presented to Special Collections and Archives in 2002 from the Dr. James A. Gibson fonds.

Leather Jacket dating back to 1967.

Brock Scarlet

The 'Brock Scarlet' Windbreaker with big blue Brock 'B' was awarded to male athletes representing Brock who were either a part of intercollegiate competition for two years or had won a championship in their first year. This particular jacket dates back to 1968.
