Why is Violence Rebounding in Mexico?

Description: This report discusses violence in Mexico fueled by organized crime cartels and the rising homicide rate which for 2017 based on preliminary reports will be above 18 per 100,000 persons. The rate in 2016 was 16.2 per 100,000. Various possible causes of the increase in violence discussed are the fragmentation of the Sinaloa Cartel, the increase in heroin trafficking and sales in the U.S., and the removal of major cartel bosses by the Mexican military leading to a power struggle in the organizations.

Preliminary Plasma Spectrometric Analyses for Selected Elements in some Geothermal Waters from Cerro Prieto, Mexico

Description: Abstract: As part of a cooperative study with the Geologic Division of the U.S. Geological Survey, water samples collected from geothermal power production wells at Cerro Prieto, Mexico, were analyzed for selected elements by d.c. argon plasma emission spectroscopy. Spectral interferences due to the presence of high concentrations of Ca, Si, Na, and K in these waters affected the apparent concentration values obtained. These effects were evaluated and correction techniques were developed and applied to the analytical values. Precipitates present in the samples at the time of analysis adversely affected the accuracy, precision and interpretability of the data.

Digital Model for Simulated Effects of Ground-Water Pumping in the Hueco Bolson, El Paso Area, Texas, New Mexico, and Mexico

Description: From abstract: The Hueco Bolson provides a substantial part of the municipal and industrial water supply of the El Paso area of Texas, New Mexico and Mexico. Although the supply of fresh ground water in the bolson is large, about 10.6 million acre-feet (13,070 hm^3) in 1973 in the Texas part of the bolson alone, the supply is being depleted.

Tin Deposits of Durango, Mexico

Description: From abstract: This report summarizes the economic possibilities of the tin deposits of the Estado de Durango, Mexico. It describes in detail many deposits in the leading districts, which were examined in 1944, and briefly reviews some reports on undeveloped occurrences in the southern and western parts of the State. The general conclusion is that tin will continue to be produced by hand methods for many years, but probably at a decreasing rate, because the placer grounds which have always produced the greater part of the tin are faced with gradual exhaustion.

Manganese Deposits of the Talamantes District Near Parral, Chihuahua, Mexico

Description: From abstract: The Talamantes district, 20 kilometers east of Parral in southern Chihuahua, has been the second largest producer of manganese ore in Mexico. Production, which started during World War I and has been more or less continuous since 1930, has totaled about 50,000 tons of ore with an average manganese content of 40 or 41 percent. The mines are on the Mesa de Talamantes, which is underlain by folded Cretaceous (?) limestone, overlain unconformably by gently dipping Tertiary rhyolite flows and tuff, volcanic breccia, agglomerate, and tuffaceous sandstone. Steeply dipping normal faults of northerly trend cut the rock and divide the mesa into a series of blocks.

Coal Deposits of the Santa Clara District Near Tonichi, Sonora, Mexico

Description: From abstract: The Santa Clara coal district is 7 to 10 kilometers west of Tonichi, a small town on the Rio Yaqui, in southeastern Sonora, Mexico. Tonichi was the terminus of a branch railroad from Corral until May 1945, when the end of the line was removed. The coal deposits were developed by the Southern Pacific Railroad from the 1890's until about 1911, when the mines were abandoned, partly because the coal was found unsuitable for use in locomotives. Other coal deposits, near Los Bronces and San Javier, west of the Santa Clara district, were mined for a number of years to provide coal for a silver smelter at San Javier which was abandoned sometime during the 1920's. Since 1942 the Santa Clara deposits have been reopened; through 1945 about 50,000 tons of coal had been shipped, at first to the Boleo copper smelter at Santa Rosalia, Baja California, and more recently to Guadalajara, Jalisco, for the manufacture of calcium carbide.
