Papers Presented at PACROFI V, Fifth Biennial Pan American Conference on Research on Fluid Inclusions, held in Cuernavaca, Morelos, Me´xico May 19–21, 1994

The nature of a geologic fluid can often be inferred from fluid-filled cavities (generally <100 μm in size) that are trapped during the growth of a mineral. A variety of techniques enables the fluids and daughter crystals (any solid precipitated from the trapped fluid) to be identified from cavities greater than a few micrometers. Many minerals, however, contain fluid inclusions smaller than a micrometer. Though inclusions this small are difficult or impossible to study by conventional techniques, they are ideally suited for study by analytical/ transmission electron microscopy (A/TEM) and electron diffraction. We have used this technique to study fluid inclusions and daughter crystals in diamond and feldspar.Inclusion-rich samples of diamond and feldspar were ion-thinned to electron transparency and examined with a Philips 420T electron microscope (120 keV) equipped with an EDAX beryllium-windowed energy dispersive spectrometer. Thin edges of the sample were perforated in areas that appeared in light microscopy to be populated densely with inclusions. In a few cases, the perforations were bound polygonal sides to which crystals (structurally and compositionally different from the host mineral) were attached (Figure 1).

I am writing this analytical appreciation of cultura panamericana, or pan-American culture, to propose a wider recognition of how its historical linkages and contemporary manifestations confront colonialism, honor indigenous roots, and reflect multiple, mixed-race identities. Although often mediated by transnational pop-culture industries, expressive cultural forms such as art and music articulate resonant themes that connect US Latinos and Latinas to Latin Americans, pointing the way toward a hemispheric imaginary. In US murals, for example, whether in the Chicago neighborhood of Pilsen or the Los Angeles neighborhood of Highland Park, pan-American expressive culture offers alternative representations by embracing indigeneity, and it creates a sense of place by tropicalizing urban spaces.
