 h English (en){{lowercase}}{{#category_index:A|anomaly}}
(&#x2202; nom&#x2019; &#x2202; l&#x0113;) <b>1</b>. A deviation from uniformity in physical properties; a perturbation from a normal, uniform, or predictable field. <b>2</b>. Observed minus theoretical value. <b>3</b>. A portion of a geophysical survey, such as magnetic or gravitational, that is different in appearance from the survey in general. <b>4</b>. A gravity measurement that differs from the value predicted by some model, e.g., a [[Dictionary:Bouguer_anomaly|''Bouguer'']] or [[Dictionary:free-air_anomaly|''free-air anomaly'']] (q.v.). <b>5</b>. In seismic usage, generally synonymous with structure. Also used for unexplained seismic events. <b>6</b>. A deviation that is of exploration interest; a feature that may be associated with petroleum accumulation or mineral deposits. <b>7</b>. An induced-polarization anomaly is usually positive and greater than background (or the <b>normal effect</b>) to be economically interesting. In the frequency domain, an anomalous region has resistivity that decreases with frequency. An interesting resistivity anomaly is generally smaller than background.
 h Spanish (es)Una desviación de la uniformidad en propiedades físicas y que a menudo es de interés en la exploración. Por ejemplo una anomalía en el tiempo de propagación, la anomalía de Bouguer, la anomalía de aire libre, etc.
