We use a novel Monte Carlo method to study the Mott transition in ananisotropic triangular lattice. The real space approach, retaining extendedspatial correlations, allows an accurate treatment of non trivial magneticfluctuations in this frustrated structure. Choosing the degree of anisotropy tomimic the situation in the quasi-two dimensional organics,$\kappa-$(BEDT-TTF)$_2$Cu[N(CN)$_2$]-X, we detect a wide pseudogap phase, withanomalous spectral and transport properties, between the `ungapped' metal andthe `hard gap' Mott insulator. The magnetic fluctuations also lead topronounced momentum dependence of quasiparticle damping and pseudogap formationon the Fermi surface as the Mott transition is approached. Our predictionsabout the `bad metal' state have a direct bearing on the organics where theycan be tested via tunneling, angle resolved photoemission, and magneticstructure factor measurement.
