First Evidence of Lamprophyric Magmatism from the Konya Region, Turkey:a Genetic Link to High-K Volcanism

In the vicinity of Konya （Turkey）,mafic,micro-porphyritic sub-volcanic rocks intrude into the Mesozoic units,which represents the only example of such a rock type in the region.40Ar/39Ar dating of two whole rock samples from the sub-volcanics gave ages of 13.72±0.13 and 12.40±0.11 Ma,suggesting temporal association to the Late Miocene-Pliocene high-K calc-alkaline volcanism in the region.The mineral chemistry and geochemical data permit us to classify the rocks as ＂minette＂ lamprophyres.They include diopside and phlogopite phenocrysts in a microcrystalline groundmass composed of sanidine,phlogopite,diopside and titano-magnetite.Segregation and ocelli-like globular structures occur commonly in the samples.In terms of major elements,the lamprophyres are calcalkaline,and potassic to ultrapotassic rocks.All the lamprophyres display strong enrichments in LILE （Rb,Ba,K,Sr）,radiogenic elements （Th,U） and LREE （La,Ce） and prominent negative Nb,Ta,and Ti anomalies on primordial mantle-normalized trace element diagrams.Geochemical data suggest that the lamprophyres and high-K calc-alkaline rocks in the region derived from a subduction-modified lithospheric mantle source affected by different metasomatic events.Lamprophyric magmatism sourced phlogopite-bearing veins generated by sediment-related metasomatism via subduction,but high-K calc-alkaline magmas are possibly derived from a mantle source affected by fluid-rich metasomatism.

Determination and Prevalence of Ticks in Cattle in Konya Province of Turkey

Ticks are common in the world.Diseases caused by ticks and fleas bring significant economic losses to the livestock industry.With the pathogens they carry,Blood-fed ticks infect humans and domestic animals.This study was conducted between January 01 and August 30,2018,in the Konya province of Turkey,to determine the prevalence and species of ticks in cattle.272 pieces of cattle were examined in terms of tick infesta­tions.These cattle were selected from herds of 16 different cattle breeders in 5 different regions of Konya.Ticks were collected by the simple ran­dom sampling method.Tick infestation was detected in 70(25.7%)pieces of cattle that were examined during the study.Tick infestation was followed in 68(29.3%)pieces female cattle and 2(5%)pieces male cattle.During the study conducted,the following results had been determined;according to age,12(14.5%)of ticks were juve­nile,58(30.7%)of them were adults,according to the body condition,26(23.4%)of them were good,35(26.1%)of them were average and 9(33.3%)of them were week.It is found that cattle in the study area were infested in the tick species Rhipicephalus(Boophilus)annulatus 65/272(23.9%)and R.bursa 5/272(%1.8).332 female and 304 male total of 636 ticks were collected from the cattle.Genders were determined under a stereomicroscope.The high tick infestation shows that fight against tick is a hard process,and plan­ning is a must to reduce the tick burden in cattle.Besides,this study will enable us to make suggestions to the relevant sectors in terms of parasitic struggle in eliminating the health and economic problems caused by ticks in the Konya province by determining the prevalence and species.
