The introduction of the airborne magnetometer in the 1940s led to the largest flow of data in geophysical history. Vacquier (1951) recognized the need for a concomitant system of interpretation of these data and pioneered the utilization of a rejected category of anomalies, the intrabasement contrasts in magnetization, for the basis of the desired system. These anomalies had great acclaim in oil and gas exploration in the late 1920s, but they led to the total disrepute of magnetics when facsimiles to the coincidence of production and intrabasement magnetization at Hobbs, New Mexico, discovered in 1928, did not achieve the same relationship. But Vacquier recognized the omnipresence of these anomalies, the singularity of individual anomalies, and their source in thick bodies of relatively steep sides and induced magnetizations. These simple but powerful deductions were reached pragmatically. To repeat, anomalies were singular because they were quite separate from one another. Therefore, the sides of their causative bodies had to be quite steep. An anomaly must be attributed to one magnetization contrast because it was one anomaly, and that magnetization was induced because the ratios of their positive and negative components correlated with the inclination of the Earth’s main magnetic field. (All of this may be found in GSA Memoir 47, 1951.)

Suicide is among the leading causes of death in the United States, and in women the second leading cause of injury death overall. Previous studies have suggested links between intimate partner violence and suicide in women. We examined female suicide deaths to identify and describe associated risk factors. We reviewed all reports from the New Mexico Office of the Medical Investigator for female suicide deaths occurring in New Mexico from 1990 to 1994. Information abstracted included demographics, mechanism of death, presence of alcohol/drugs, clinical depression, intimate partner violence, health problems, and other variables. Annual rates were calculated based on the 1990 census. The New Mexico female suicide death rate was 8.2/100,000 persons per year (n = 313), nearly twice the U. S. rate of 4.5/100,000. Non-Hispanic whites were overrepresented compared to Hispanics and American Indians. Decedents ranged in age from 14 to 93 years (median = 43 years). Firearms accounted for 45.7% of the suicide deaths, followed by ingested poisons (29.1%), hanging (10.5%), other (7.7%), and inhaled poisons (7.0%). Intimate partner violence was documented in 5.1% of female suicide deaths; in an additional 22.1% of cases, a male intimate partner fought with or separated from the decedent immediately preceding the suicide. Nearly two-thirds (65.5%) of the decedents had alcohol or drugs present in their blood at autopsy. Among decedents who had alcohol present (34.5%), blood alcohol levels were far higher among American Indians compared to Hispanics and non-Hispanic Whites (p = .01). Interpersonal conflict was documented in over 25% of cases, indicating that studies of the mortality of intimate partner violence should include victims of both suicide and homicide deaths to fully characterize the mortality patterns of intimate partner violence.
